Distribution Of Obesity In Women And Men Is Different

The distribution of obesity in women and men is different, when they gain weight on a low fat/high carb diet. The distribution of fat follows a pear shape in women due to fat accumulated around the hips. In males excessive fat accumulates around the waist, which gives them an apple shape appearance.

Researchers at the University of California, Riverside (UCR) have done experiments using a mouse model. They wanted to see what changes take place when obesity develops. Djurdjica Coss was the lead researcher of the study from the UCR School of Medicine.

The reason why this study was thought to be necessary

Many men and women have relatively normal weights until their mid 50’s. But when women approach menopause, they tend to accumulate fat in the thigh areas (pear-shape obesity). When their weight continues to rise, they also accumulate weight in the abdominal area. It is general knowledge that the fat in the abdominal region is metabolically more active producing inflammatory kinins.

Men above the age of 50 or 60 are also accumulating fat, but typically in the abdominal area right away. The name for this is apple-shape obesity. Unfortunately this is the fat we just discussed, metabolically active with inflammatory kinins. It is known to be the cause for heart attacks and strokes as it accelerates hardening of the arteries in the whole body. Dr. Coss found in doing experiments on mice that estrogen plays a major role in the development of obesity as discussed below.

The mouse experiments to study the development of obesity

The research team of Dr. Coss compared a group of mice that had their ovaries taken out. The ovaries in females are the main source of estrogens. They fed them a high-fat diet comparing their weight gain to that of male controls on the same diet. Obesity leads to a change in metabolism, called metabolic syndrome. This condition has an association with the production of inflammatory substances originating from the abdominal fat accumulation. Both male and female mice underwent a series of blood tests. They were also physically inspected. The female mice had the pear-type accumulation of fat, the males an apple-type fat accumulation.

More details about what obesity did to the experimental mice

In males there was a reduction of sperm count in the obese group as well as low muscle strength. In addition they were low in energy, had a lack of libido and their testosterone levels were low. The sperm number and the testosterone level had fallen to 50% of what they were when their weight was normal. This is what happens in human obese males as well. The inflammatory substances, that the abdominal fat creates, broke down the blood/brain barrier, and this affected the brain.

Among the female mice there was no neuroinflammation in the brain. There was no change in their hormones, which was quite a remarkable finding. This was a surprise and points out that beside estrogens there are other mechanisms to protect females from the effects of obesity.

Brain inflammation from obesity

Dr. Cross explained that in male mice the fat accumulation was of the apple-type. Female mice had the pear type fat accumulation. The fatty tissue in females did not release inflammatory kinins. On the other hand, the abdominal fat in the males released inflammatory kinins. These attracted macrophages, which is a cell type of the immune system. Activated macrophages now became aggressive and broke down the blood/brain barrier. This resulted in neuroinflammation of the brain. The brain normally is an immune protected site because of the blood/brain barrier. When this breaks down because of the action of inflammatory kinins from abdominal fat, the brain starts to develop memory loss like in Alzheimer’s disease.

Women before and after menopause

In females who still produce enough estrogen, fat from the pear type obesity distribution does not produce inflammatory kinins. This explains the relative protection of premenstrual women from heart attacks and neuroinflammation. But menopausal women start accumulating fat around the abdomen as well. At that point they can also develop inflammatory kinins and neuroinflammation. This is why the heart attack and stroke rate increases in postmenopausal women with apple-shape obesity.

Other studies supporting the effects of obesity in men and women 

Inflammatory substances in obese people affecting their brain

This publication shows that in a group of 141 neurologically healthy obese individuals the anti-inflammatory defense in the brain was weakened. Subsequently, various brain conditions developed because of the inflammatory substances affecting the brain.

How obesity affects your body functions

Obesity affects the body in various ways. It is particularly the apple type obesity that causes inflammatory substances circulating in the blood. A multitude of conditions can develop from this.

  • The cholesterol shows an increase of the bad LDL cholesterol and a reduction of the good HDL cholesterol.
  • The blood pressure rises. Without treatment high blood pressure can cause strokes.
  • Type-2 diabetes often develops because the insulin production cannot keep up with the demand. A second factor is a loss of insulin receptor sensitivity. As a result the insulin receptors of the body cells become resistant to insulin.
  • The gallbladder often develops stones, which may require gallbladder surgery.
  • Some cancers are increasing in frequency: endometrial cancer, breast, colon, kidney, gallbladder, and liver cancer.
  • Anxiety, depression and other mental disorders are more common, in part because of the neuro-inflammatory processes that I mentioned before.
  • Body pain and problems with physical functioning: obese people have more back pains, hip and knee pains from the extra weight. Slim people are less likely to have these problems. Obese people require more hip and knee replacement surgeries for end-stage arthritis than slim people.

Difference of metabolism in pear-shape versus apple-shape obesity

Back to the pear versus apple distribution of fatty tissue in obesity. diabetes, heart disease, high blood pressure and strokes as the apple type obesity. The difference in metabolism between the two is explained in detail here.

Conclusion

You may have heard that women tend to accumulate fat more around their hips, possibly because of hormonal factors. This is a pear-type fat distribution. In men who turn obese the fat accumulation follows an apple pattern. This type has a more aggressive metabolism in the fat tissue with inflammatory kinins accessing the blood circulation. It also affects the blood/brain barrier. Normally this barrier does not allow proteins to enter the brain. But when a person is obese, inflammatory kinins and proteins can enter the brain freely causing mental illnesses like depression and anxiety. Many obese people also develop type-2 diabetes leading to heart attacks and strokes.

Low fat diet from the 1980’s

The low fat diet of the 1980’s has caused a lot of obesity around the world. The problem is that merchants who provide low fat products have replaced fat with refined sugar. The liver converts refined sugar into fatty acids and triglycerides. These end up as fatty tissue. Given enough time this is causing obesity. Those who are obese need to cut out refined sugar in its many disguises. In addition they also need to cut down their starchy food intake. In the gut starchy foods break down into sugar.

When you cut out sugar and starchy foods, a person will typically lose 50 pounds in 3 months, at which point they have lost the label of “obesity”. They will also feel more energetic. The best advise for you is to maintain your weight loss with a Mediterranean diet. Research studies have shown that it is beneficial and anti-inflammatory.

No Amount Of Alcohol Is Good

New research, more extensive than previous research has shown that no amount of alcohol is good.

This is completely against the widespread belief that moderate consumption of alcohol would prevent heart disease.

Specifically, previous research had shown the following: one glass of alcohol per day for women and 2 glasses of alcohol for men was reportedly make us live longer.

New research with larger population numbers

But a new study involving much larger population groups, all ages, and drinkers versus non-drinkers came to a different conclusion. It concluded that the previous recommendation was based on only heart attack rates, but excluded other causes of sudden death like heart failure, a rupture of the aorta (aneurysm), high blood pressure that kills (fatal hypertensive disease) and strokes. With the compilation of all these cardiovascular diseases, the statistics suddenly started to look different. Now even small amounts of alcohol killed. What is worse, there was clear evidence that binge drinkers have much worse survival statistics than moderate drinkers. When you drink according to the American Heart Association’s recommendation, you drink smaller amounts of alcohol daily.

Binge drinking

But many of us like to live it up on weekends or whenever there are friends over who also like a few drinks. This binge drinking habit lowers the life expectancy by an average of 10 years. It does so because the list of complications I mentioned above. In addition there are alcoholic liver cirrhosis, pancreatitis and various cancers that shorten your life.

Global health study

The funders of this global health study was the Bill and Melinda Gates Foundation, and it looked at the burden that alcohol puts on 195 countries. The original study appeared in the Lancet. The combined study population was 28 million individuals. There were 649,000 cases of various deaths due to alcohol. Here is a summary of the abbreviated outcome of the global health study. As you can see from this, there is no safe level of alcohol consumption as even small amounts of alcohol over a long period of time lead to significant damage in the body. You can prevent heart attacks to a certain extent. But instead people die from a ruptured aorta, from strokes or from heart failure. The leading cause of death for men and women age 15 to 49 worldwide was alcohol. It accounted for almost 1 in 10 deaths.

Some alcohol-related statistics

The following were the observaions in the study.

  • Over 300 disabilities and diseases were directly related to alcohol consumption. The findings were collected in 195 countries, classified by age and sex. The data was gathered between 1990 and 2016.
  • Globally, 2.4 billion people drink alcohol. 25% are women who consume 0.73 drinks on average each day, 39% are men drinking 1.7 drinks a day.
  • Denmark, Norway and Germany drank the most alcohol globally.
  • For ages 50 and up the leading causes of death were: road injuries, suicides and tuberculosis.

More statistics

  • Most deaths caused by alcohol came from cardiovascular disease and cancer for all countries.
  • When you look only at drinkers, the standard recommendation of the American Heart Association regarding low alcohol consumption seems true. But the new study compared non-drinkers with drinkers. From this it is clear that even one drink a day has a risk of premature death.
  • At the age of 40 cutting down long-term alcohol use will add 1 to 2 years of life expectancy.
  • For all ages 2.8 million people die globally every year from alcohol related diseases.
  • Half of the world does not drink at all. This means that the ones, who drink, consume double as much as the statistics show.
  • Americans prefer beer. They drink about 27 gallons of beer, 2.6 gallons of wine and 2.2 gallons of spirits per adult/year.

Common clinical conditions from alcohol consumption

Binge drinking is the consumption of 5 drinks or more in an evening for men or 4 drinks for women. The CDC is concerned about binge drinking, because of its association with significant organ damages. There are 4 major concerns regarding these effects. Heart disease and cancer; diabetes; memory loss and appearance. In the following I will zero in on these alcohol-related conditions. 

Heart disease

As this article pointed out above, there is a very limited protective effect, but mostly in above 55-year-old women who drink in moderation (1 glass of alcohol; per day). They have some protection from developing heart attacks, because their LDL cholesterol gets lowered and their clotting system is influenced in positive ways. But 6% of breast cancer in women is due to the effect of alcohol consumption, which is a downfall. For both men and women binge drinking is what kills. Binge drinkers who drink more than 100 grams of alcohol per week (more than 7 drinks in the US) experience increased deaths. The causes are heart failure, strokes, fatal hypertensive disease and fatal aortic aneurysm, where the main artery bursts. Apart from that alcohol-related pancreatitis and liver cirrhosis can kill as well.

Cancer

A relatively new finding is that alcohol has a close relationship to causing various cancers. Alcohol weakens the immune system. Also, alcohol has a negative influence on the bacterial composition, the microbiome in our digestive tract, is. This can be a cause for colon cancer. Liver cancer, mouth cancer and breast cancer also has a direct relationship to increased alcohol consumption. Esophageal cancer and laryngeal cancer are also related to alcohol consumption.

Diabetes

Alcohol can stimulate the pancreas to release insulin, which may give you hypoglycemic attacks. As alcohol contains empty calories, over the course of several years alcohol consumption can add to your weight, causing obesity and type 2 diabetes. As diabetes has detrimental effects on the heart and blood vessels, this mixed with alcohol consumption, can worsen cardiovascular disease thus increasing the risk for heart attacks and strokes.

Memory loss

In the beginning of chronic alcohol consumption you may enjoy the relaxing effect of alcohol. This is merely the toxic effect of alcohol on brain cells. Alcohol has the effect of inhibiting brain cells, which makes you feel relaxed, super-sociable and even silly. In reality you are starting to loose control. After several years of this effect you are left with feelings of anxiety, depression and anger. This is when trouble starts to occur. People out of control are more likely to get into fights and get injured or killed. People can develop blackouts where they do not remember parts of the evening or an entire event. Memory loss is starting. The hippocampus is an important part of the brain that is involved in processing short- term memory into long-term memory. A form of dementia can occur that was brought on by chronic alcohol overconsumption.

Appearance

Alcohol dries out the skin cells and body cells. The face gets wrinkles. Your skin looks parched and gives you the appearance of a prematurely aged person. Alcohol can interfere with your sleep and when you have a lack of it you end up with dark circles around your eyes as well as puffy eyes. It does not make for a good picture, whether it happens inside the body or on your skin!

No Amount Of Alcohol Is Good

No Amount Of Alcohol Is Good

Conclusion

A new study that was larger and more comprehensive than any previous study has exposed the myth that one drink for women and two drinks for men would protect you from heart disease. It may protect you from heart attacks, but it definitely does nothing to protect you from other heart conditions. There is also sudden death from heart failure, a rupture of the aorta (aneurysm), high blood pressure that kills (fatal hypertensive disease) and stroke. When you factor all that in as well, even your low, moderate alcohol consumption has health risks. The global health study, funded by the Bill and Melinda Gates Foundation looked at the burden that alcohol puts on 195 countries. The combined study population was 28 million individuals.

Alcohol related deaths and diseases

649, 000 registered cases of various deaths occurred due to alcohol. This included deaths from traffic accidents, injuries, cancer, heart disease and suicide. This global study compared the life expectancy and disease frequencies of alcohol-consuming people with non-alcohol consuming people. It concluded that non-alcohol consuming people live on an average up to 10 years longer than their alcohol-consuming counterparts. No studies up to now have been that comprehensive. The results from twenty-eight million people speak for themselves, and the death statistics are clear. It is worthwhile to look at the details and draw your own conclusion.

The Best Foods For Your Heart

In the following I will describe 16 foods, which are the best foods for your heart. I will also comment as to why I believe they are best. This review is based on this article in “Medical News Today”.

But I have added many other comments to it.

Heart disease is still the number 1 killer. We need to change what we eat.

Vegetables

The regular intake of green leaf vegetables and cruciferous vegetables (broccoli, cauliflower and cabbage) has an association with the  preservation of cognitive function. In the Nurses’ Health Study starting in 1984 women were asked about their usual intake of a specified portion of food items, including 15 fruits and 28 vegetables. At a later date, between 1995 and 2001, researchers decided to ask the oldest participants (70 years and older) to participate in a cognitive function study. Two years later researchers repeated these tests.The main finding of the study is that women with the highest intake of green, leafy vegetables had the least decline in their cognitive function. The vegetable lovers, who consumed five serving of cruciferous vegetables, like broccoli, cabbage and cauliflower had less decline in their cognitive function. On the other hand the highest decline showed up in the group that averaged only 2 servings per week.

Asparagus

Asparagus is a source of fiber, folate, multiple vitamins and chromium. Chromium enhances the function of insulin to transport sugar into cells. Asparagus contains glutathione, a powerful antioxidant that neutralizes free radicals and carcinogens. It is said to help prevent lung cancers, larynx cancer, and bone, breast and colon cancers.

Berries

Berries like strawberries, raspberries, blackberries and blueberries are full of bioflavonoids. These are antioxidants, which prevent cardiovascular disease.

It is the anthocyanines, which prevent oxidation of LDL cholesterol. Berries also have bioflavonoids and reduce lipid formation in the blood. Berries contain fiber, folate, iron, calcium, vitamin A, and vitamin C.

Broccoli

This fiber rich vegetable helps to prevent hardening of the arteries. Broccoli and kale likely have preventative effects against colon cancer.

Chickpeas, beans, peas and lentils

Legumes or pulses are a great way to consume plant-derived protein. People who are on vegan diets should be eating them for a protein source. They also contain lots of fiber, vitamins and minerals. We know that they lower cholesterol, which prevents heart disease. Other healthy nutrients they contain are bioflavonoids, which have antioxidant properties and help prevent cardiovascular disease.

Dark chocolate

This is a food rich in antioxidants. Dark chocolate is chocolate with more than 70% cocoa content. Please note: “milk chocolate” is nothing better than candy and devoid of any health benefits. Dark chocolate increases the protective HDL cholesterol and prevents oxidation of LDL cholesterol. It is said to prevent atherosclerosis (hardening of the arteries). Don’t exceed eating 1 to 2 oz. per day, as chocolate has some sugar in it and the fat content would be detrimental with higher consumption.

Chia seeds and flaxseeds

Chia seeds and flaxseeds are rich in omega-3 fatty acids in the form of α-linolenic acid (ALA). ALA reduces LDL cholesterol and it dissolves plaque in the arteries. ALA also reduces blood pressure to a certain degree. All of this helps reduce cardiovascular disease (heart attacks and strokes). Note that flaxseeds must be ground to powder to release the nutrients from its tough shell. Both chia and flaxseeds can be used as an egg replacement in vegan cooking.

Fish high in omega-3s

Omega-3 fatty acids are abundantly present in fish. It has plaque-reducing properties and also reduces the risk for abnormal heart beats. Overall this means less cardiovascular disease. The American Heart Association recommends a 3.5 oz. serving of fatty fish (salmon, mackerel, lake trout, herring or sardines) twice per week.

Coffee

A Brazilian study from 2018 showed that drinking 3 cups of coffee a day would stop coronary artery calcification. Many other studies have shown reduced mortality from heart attacks and strokes with increased coffee intake.

Green tea

Green tea is known to reduce blood pressure slightly and to reduce cholesterol. Both effects are beneficial for the cardiovascular system (prevents heart attacks and strokes). Green tea also prevents many cancers. Whatever we know about coffee consumption seems to also be true for green tea consumption.

Nuts

Nuts contain healthy fatty acids (omega-3). But they also contain fiber, protein, minerals, vitamins and antioxidants. Use them in desserts, in salads and as a quick food on the go. They are definitely healthier than protein bars.

Liver

Liver is one of the nutrient rich foods. It is rich in iron, phosphorus, vitamin A, folate, vitamin B12 and biotin.

Oatmeal

Oatmeal is rich in soluble fiber. It has been shown to lower LDL cholesterol and total cholesterol. This is important for prevention of heart disease.

Red wine (may be)

The bioflavonoids of red grapes have been the subject of much research. There is a dose-response curve showing a protective effect with regard to heart attacks and strokes with the consumption of  1 to 3 glasses of red wine per day. But unfortunately there is also a dose-response curve with respect to alcohol consumption and cancer causation. Personally, I take resveratrol from the health food store, 500 mg daily and consume white wine or red wine very rarely.

Tomatoes

There are a number of beneficial phytochemicals in tomatoes. Carotenoids like lycopene, lutein, zeaxanthine and beta-carotenes are helping to prevent prostate cancer and colon cancer. Potassium and folate are cardioprotective.

Spinach

Eating spinach regularly will provide you with magnesium, iron and bioflavonoids. Magnesium is good for a regular heart rhythm. The other nutrients are good for skin, bone and hair health.

Discussion

I have reviewed why these 16 foods are the best foods for your heart. We have seen that many foods that are rich in antioxidants are also cancer preventative. People who eat a Mediterranean diet will get these 16 foods, because their meals are balanced with nutrients. But if you eat a hamburger or a pizza you will not get balanced nutrients. The more one-sided your food intake, the more dangerous your lifestyle becomes. This is the problem with the Standard American diet (“SAD”). You need all of the components of the 16 foods described here. Junk food won’t do, as it consists only of empty calories.

The Best Foods For Your Heart

The Best Foods For Your Heart

Conclusion

It is useful to review healthy foods as was done above. Now it is a matter of including them in your daily food intake. If this is overwhelming you, start with baby steps. One or two healthy foods here or there are a good start. Increase this until you cover all the 16 foods mentioned. The more balanced your food intake is, the more antioxidant vitamins you will get. And the more heart disease and cancer prevention you will experience.

Apart from good, balanced nutrition we also need regular exercise for heart disease and cancer prevention. Go to a gym, go for a walk, climb some stairs. Get away from the computer and television. Together with best foods for your heart this will keep you healthier for longer.

Cell Phones Can Cause Cancer After All

Re-investigation of whether or not cell phones can cause cancer revealed that cell phones can cause cancer after all. This publication comes from the Journal “The Guardian”. It turned out that for 25 years the cell phone industry managed to suppress scientific evidence of cancer. In many experiments scientists found brain cancer and adrenal gland cancer in rats from exposure to electromagnetic fields. Regulatory authorities based their statements on fake experiments that showed no apparent effect of EMF (electro-magnetic fields) on animals. There were never any human trials. But 25 years ago cell phones received a “clear signal” though in retrospect that was wrong. Now it turns out that this is one of the biggest human mass experiments.

Human cancer statistics

Exposure to radiation from an atom bomb can indeed bring on brain tumors. This Australian study investigated brain cancer rates in the 1980’s and in the early 2000’s. The conclusion was that cell phone exposure was a bout the same in  the 1980’s and the early 2000’s. Brain tumors were also the same. But at the bottom of this review the authors show some interesting statistics about Hiroshima. Brain cancers are shown as bar graphs in people who suffered exposure to the radiation of Hiroshima. The bar graphs compared brain cancer statistics between 31 years after Hiroshima and 41 to 50 years after Hiroshima. There still was a clear increase of brain tumors in the population 41 to 50 years after Hiroshima.

Long lag time

This is because brain cancer has a long lag time between radiation exposure and actual brain cancer occurrence. The prominent Sydney neurosurgeon, Dr. Charlie Teo said that there can be a long lag period of 10 to 20 years for electromagnetic frequencies (EMF) to cause brain cancer. EMF also has the name EMR (electromagnetic radiation). If one takes into account that EMF is much weaker than radiation from an atom bomb, the lag period of causing brain cancer could be much longer than what Dr. Teo assumed.

An international study found that gliomas were 40% more common in high cell phone users than in low cell phone users. For meningiomas the high cell phone users had 15% more meningiomas than low cell phone users. A previous British study assuming a lag period of 10 years found no gliomas in children and young persons as I reported 12 years ago. But this data might change with a lag period of 20 or 30 years or longer.

Political manoeuvres

The cigarette industry did not want to admit that cigarette smoke was causing lung cancer. In a similar vein the cell phone producers attempted to suppress any negative information about their products. They have been suppressing information that found any biological effect of EMF on tissues. And they funded studies that showed no effect by EMF.

The Guardian states: “The key strategic insight animating corporate propaganda campaigns is that a given industry doesn’t have to win the scientific argument about safety to prevail – it only has to keep the argument going. Keeping the argument going amounts to a win for industry, because the apparent lack of certainty helps to reassure customers, fend off government regulations and deter lawsuits that might pinch profits.” By pursuing this strategy over 30 years the industry has been very successful to undermine any scientist who found that cancer of the brain and cancer of the adrenal glands can occur after prolonged exposure to EMF.

What is the truth about EMF? 

The National Cancer Institute

The findings of the National Cancer Institute review are that there is no evidence that the exposure rate or intensity of EMF is strong enough to pose any risks to children or adults. It did acknowledge that exposure to living within 1 kilometer of high voltage power lines could cause leukemia in children. But EMF exposure is not comparable to EMF from these high power lines. The problem with the attitude of the National Cancer institute is that they don’t mention how the lag period can delay the occurrence of cancer by several decades. In other words, their observation time was cut short, and they simply concluded prematurely that EMF could not cause cancer.

World Health Organization

The WHO has done a thorough review of the world literature on the topic of EMF and possible effects on humans. It did acknowledge that the top 10% of heavy cell phone users are at a higher risk of gliomas and meningiomas as mentioned above. EMF exposure has to last for at least 10 years for this to occur. But the vast majority of cell phone users show no effect on the brain or elsewhere. The WHO makes the point that brain cancers may be more common, if EMF exposure to a person is 10 years or longer. The International Agency for Research on Cancer has classified EMF as “possibly carcinogenic to humans”. It means that more exposure, longer duration of exposure, and closer tissue contact with EMF could cause cancer.

Cancer literature supports that cell phones can cause cancer after all

In a website by Prof. Keith Scott-Mumby several factors come up that support the notion that EMG is capable of causing DNA damage to cells given the right circumstances.

  • Children are much more vulnerable in their brains than adults to get brain cancer. As a result, when children play with cell phones and other gadgets that emit EMF they will be more likely to develop brain cancer later in life.
  • Acoustic neuromas in the auditory nerve are 5-fold more likely to develop in children than in adults.
  • Swedish researcher, Prof. Lennart Hardell presented a talk at a cancer conference, which stated the following: People who started to use cell phones before the age of 20 had a 5-fold risk to get gliomas, which is a brain cancer type.
  • Other research showed that exposure of children to EMF from cordless phones in a household caused a 4-fold higher risk of developing gliomas later in life than controls who did not have EMF exposure.
  • Keith Scott-Mumby also stated that brain tissue of children absorbed EMF twice as much as adults do, and similarly, bone marrow of children absorbed EMF 10 times as much as adults do.
  • An Indian study in 2005 was comparing people who had no EMF exposure with people who used a cell phone for 1 to 15 hours per day. DNA damage was measured from buccal scrapings (the lining inside the cheek). The controls had only 4% of DNA damage. The frequent cell phone users had DNA damage in 39.75% of their buccal scrapings. We know from other literature that the first step to developing cancer is a mutation of the DNA. After a certain lag period cancer can develop in tissue with mutated DNA.
Cell Phones Can Cause Cancer After All

Cell Phones Can Cause Cancer After All

Conclusion

EMF, the low-grade radiation of electronic gadgets like i-phones, cell phones in general and cordless phones, has an effect on our body cells. We are not aware of this effect. But the body knows on a cellular level that part of our DNA has been damaged. Fortunately, we do have protective mechanisms in place that safe us from most of these damages. But children who are not fully developed yet are at a disadvantage. Their bone marrow and brains are much more prone to develop various types of leukemia and brain cancers. This is why it makes sense to limit their exposure to EMF emitting devices.

At this point the government institutions have not developed recommendations what to do about this problem. The industry has no interest in providing guidelines, as they want to sell more gadgets and increase their market share.

Add to this that even the wiring in a house is sending out weak signals of EMF, which is added to all of the other effects of EMF from cell phones, TV and computer use. We need to rethink our exposure to EMF and balance our lifestyle with other activities where we are not subject to this exposure.

We also need to eat an anti-cancer diet, like a Mediterranean diet. This diet has shown to be an anti-inflammatory and antioxidant diet preventing cancer. All of this can balance our exposure to EMF and offer us preventative measures to stay healthy.

The Downside Of Living To 100

A review article has examined longevity and reviewed the downside of living to 100. In their 80’s about 10% of the population live in nursing homes, but among centenarians 55% are residing in nursing homes. They are often very lonely, as their social circles have shrunk as they aged.

Common diseases of older people

Osteoarthritis makes it difficult for people to get around, it causes chronic pain and it can also be the reason for falls. In 1990 there were 213.4 cases of osteoarthritis per 100,000. 26 years later, in 2016 there were 232.1 cases of osteoarthritis per 100,000 people.

Chronic obstructive pulmonary disease (COPD) has been falling, because less people smoke cigarettes now. Statistics show 1667 cases of COPD per 100,000 in 1990, but only 945 cases of COPD per 100,000 in 2016.

Diarrhea and common infections have dropped sharply from 8951 per 100,000 in 1990 to 3276 per 100,000 in 2016.

What other common diseases do older people get?

There are a number of common diseases that affect the elderly.

Osteoarthritis

Osteoarthritis of the hips and the knees are common, but it can affect every joint in the body. In the end stage knee replacements or hip replacements may be necessary. But before a total knee replacement or total hip replacement can even come into consideration, the person’s heart needs a thorough checkup to ensure that it is safe for the patient to undergo surgery under a general anesthetic.

Heart disease

Older people often have heart disease.

When coronary arteries are narrowed, heart attacks occur. Cardiologists can place stents, so that previously narrowed coronary arteries receive normal blood flow. Following such a procedure the patient may live for another 10 to 15 years.

There are also heart valve calcifications. The aortic valve is particularly endangered. A heart surgeon may be able to replace a diseased aortic valve by a porcine valve.

The nervous system of the heart transmits electrical signals from the sinus node to the muscle fibers, which can get diseased. Heart rhythm problems may necessitate the insertion of a pacemaker.

Finally, the heart may enlarge, but pump less blood than before. This condition is congestive heart failure. The 5-year survival for this condition is only 50.4%. Unfortunately there is very little the doctor can do for patients like this.

Cancer

The older we get, the more DNA mutations we accumulate. At one point cancer develops. If the diagnosis happens at an early stage there is a good chance that surgery can remove a cancerous growth, and the patient survives. But there are cancers that are notoriously difficult to recognize in the early stages. These are: cancer of the pancreas, kidney cancer, stomach cancer and certain types of leukemias.

Respiratory diseases

Those who smoked earlier in life may develop chronic obstructive pulmonary disease (COPD). It is a chronically disabling lung disorder. Often these individuals have to carry an oxygen tank with them wherever they go. The 5-year survival rate for people with COPD is 40 to 70%.

Osteoporosis

Osteoporosis is a disease where the bone is brittle. Spontaneous bone fractures can occur at the wrists, the upper thigh bone (femoral fractures) or in the vertebral bones. Women in menopause are hormone deficient and this contributes to calcium depletion of the bones. Lately research has shown that vitamin K2 and vitamin D3 are necessary for a normal calcium metabolism. Briefly, 200 micrograms of vitamin K2 and 5000 IU of vitamin D3 every day are the necessary dosage that the body can absorb calcium from the gut, eliminate it from the blood vessels and deposit it into the bone. Calcium is present in milk products and milk. If a person does not consume enough milk products a supplement of 1000 mg of calcium daily does make sense.

Alzheimer’s

The older we get, the more likely it is an onset of Alzheimer’s or dementia. Between the ages of 90 to 94 there is a yearly increase of Alzheimer’s of 12.7% per year. The group from age 95 to 99 years has a yearly increase of Alzheimer’s of 21.2% per year. Persons aged 100 years and older have an increase of Alzheimer’s by 40.7% per year. What this means is that essentially there is a doubling of Alzheimer’s every 5.5 years. We do not have all of the answers why this is happening and why Alzheimer’s develops. But we do know that diabetics are more likely to develop Alzheimer’s. High blood sugar levels and high insulin levels seem to lead to the precipitation of the tau protein in the brain, which causes Alzheimer’s.

Diabetes

When diabetes is not well controlled, there is accelerated hardening of the arteries. This can cause heart attacks and strokes. Longstanding diabetes can affect the kidneys (diabetic nephropathy, kidney damage) and can lead to hardening of the leg arteries. Often the only treatment left is a below knee amputation. Blindness from uncontrolled diabetes is common and pain from diabetic neuropathy as well.

Diabetics have an average life expectancy of 77 to 81 years. However, if they pay attention to their blood sugars and manage their diabetes closely they can live past the age of 85.

Falls and balance problems

As people age, their balance organ is not functioning as well. Also, people with high blood pressure medication may have postural hypotensive episodes that can lead to falls.

There may be a lack of cognitive functioning and misjudging of steps, ledges and irregularities in the floor. When a person has brittle bones from osteoporosis and they fall, a hip fracture is very common. At a higher age surgery for a hip fracture is dangerous. It can have a mortality of 50%.

Obesity

A person with obesity has a life expectancy that is 10 years less than a person without obesity. The reason for this is that with obesity This is so, because the risk of heart attacks, strokes, cancer, arthritis and diabetes is increased.

Depression

Older people often get depressed. It even has its own name: involutional depression. People can get into a state of mind, where they think negatively. Depressed people feel that they have nothing to live for. They lost friends; they are shut in because they can’t drive a car any more. This type of depression needs treatment by a psychologist or psychiatrist. The danger of leaving depression untreated is that the person may get suicidal. In older people depression is often precipitated by physical health problems.

Oral health

When teeth are not looked after, gingivitis and periodontitis can develop. Infected gums can shed bacteria into the blood and this can affect the heart valves. Endocarditis, the infection of heart valves, is a cardiological emergency. Prolonged antibiotic therapy is necessary to overcome this condition.

Poverty

Poverty has real consequences. The aging person may not have access to the optimal medical care facility because of a lack of funds. But even at a younger age there is evidence that people are healthier when they are wealthier.

Shingles

Older people often get shingles, even if they had chickenpox or shingles as a child. This is evidence that the immune system is getting weaker. Shingles in an older person should alarm the treating physician that there could be an underlying cancer. Due to that knowledge a cancer-screening tests should be part of the medical exam. In addition, a varicella vaccine should be offered to the patient to build up immunity.

The Downside Of Living To 100

The Downside Of Living To 100

Conclusion

Living to 100 is often glorified in the press. Maybe you have seen a 90-year old jogger completing a marathon, or you saw an 85-year old couple ballroom dancing. But what they don’t show you is what I summarized here, the less glamorous things about living to 100. You may get a heart attack or a stroke. Osteoarthritis may affect you how you walk. Congestive heart failure may make you get short of breath when you walk upstairs. Then there are various cancer types that are difficult to diagnose early.

If you have smoked in the past, you may suffer from chronic obstructive pulmonary disease (COPD), which leaves you breathless.

Other illnesses

Osteoporosis can lead to spontaneous fractures. Because the bone has a lack of calcium, this is difficult to treat and takes a long time to heal.

Alzheimer’s is ever so much more common when you approach the year 100. There are other medical conditions you can get: obesity, diabetes and depression. When you get shingles for the second time, it may mean that your immune system is getting weak and a cancer-screening test should be done.

There are some downsides when you approach the age of 100.

Know your risks and be vigilant

You may keep your physician busy checking out various age-related illnesses, but more importantly, get regular check-ups and tests. Any condition is easier to treat with an earlier diagnosis! The message for anybody reading this is very simple. Prevention through healthy living is something you can actively pursue. Keep your body and your mind busy. Enjoy time with friends and family instead of living a solitary existence. See the glass that is half full instead of viewing it as half empty. Stick to a healthy diet. Knowing all the risks is not a scare but a call to being vigilant. Knowledge is powerful and will help you to enjoy your golden years feeling well and happy.

HPV Testing For Cervical Cancer

HPV testing for cervical cancer is more sensitive than the traditional Pap test. For years physicians recommended the traditional Pap test once a year to prevent cancer of the cervix. But a few years ago a new cervical cancer screening test, namely the HPV test made the news. It stems from the observation that cancer of the cervix develops in 99.7% of women who test positive for the HPV virus. There are many types of HPV, here we are interested in the few subtypes that produce cancer (carcinogenic HPV virus).

Transmission of the HPV virus between men and women

The human papilloma virus transmits from males to females through bisexual contact. The problem starts when he develops HPV lesions on his penis. Without him wearing a condom, the contact with her cervix during sex can transmit HPV to her cervix. Both partners are not aware of the transmission of that virus, as it does not cause any symptoms. HPV invades the superficial skin layer of the cervix in the woman. In the man HPV will invade the skin of the glans of the penis. After certain incubation time it causes transformation into cervical cancer in the woman. Strangely enough it does not cause cancer in the male. However, in both sexes HPV virus is in the mucous membranes and can contaminate the other sex’s genital.

A recent study comes from UBC Vancouver, British Columbia, which compared the Pap test with HPV testing.

Details of the Vancouver study on HPV testing for cervical cancer

On July 3, 2018 this study appeared in the medical journal JAMA.

19,009 women were part of this randomized clinical trial. With HPV testing only 2.3 cases per 1000 women of early cervical cancers were present four years later. Using the traditional Pap test this figure was 5.5 cases per 1000 women after 4 years. 224 clinicians participated in this study. Women were recruited for this study from January 2008 to May 2012. Follow-up took place till Dec. 2016. The participating women in this study were 25 to 65 years of age.

In 2017 in the US there were still 12,820 women in the United States who got cancer of the cervix. Approximately 4210 are dying from this disease every year. Many women do not like to take the Pap test or the HPV testing. There are compliance problems with either one of these tests.

Significance of this trial regarding HPV testing for cervical cancer

The newer HPV testing was superior to the regular Pap test. The HPV test was more sensitive and resulted in much lower cancer rates after 4 years of follow-up. Every woman would have an HPV test every 4 years. In this case we likely would see cervical cancer go to the bottom of cancers that kill women. The reason for that is that HPV testing and colposcopy pick up cancers much earlier. This leads to a more effective treatment of cervical cancer. After 4 years much less cancer of the cervix was found when the researchers tested again using HPV testing.

Implications of HPV testing for cervical cancer

In third world countries

Many 3rd world countries do only the HPV testing. At the time when this decision was made, it was unknown that they had actually chosen the better method to test for cancer of the cervix. Now this trial reassures all the health care providers in 3rd world countries that they should continue with the program, and they only have to do the test every 4 years, not every 2 years, which makes it even more cost effective.

Implications for the US

In the US so far the recommendation was to do both the regular Pap test and the HPV test simultaneously. This trial, however, says that this is not necessary. It would be better to use the more sensitive HPV test and abandon the more expensive and less sensitive PAP test. In 2012 a taskforce recommended to do the Pap smear in women age 21 to 65 every 3 years. The taskforce further recommended to women age 30 to 65 that they screen with a combo of cytology and HPV testing every 5 years. The lead investigator, Dr. Ogilvie said: “Offering women HPV [testing] for cervical cancer screening detects more precancerous lesions earlier, and also a negative HPV test offers more assurance that women will not develop precancerous conditions in the next four years,” she said. “This can mean that women may need less frequent screening but have more accurate results.”

What other doctors are saying about HPV testing for cervical cancer

Comments by Dr. Kathleen Schmeler

Dr. Kathleen Schmeler said that the study was “well-designed” and provided a much-needed comparison of Pap versus HPV testing. She is a gynecologic oncologist and at The University of Texas MD Anderson Cancer Center. She was part of the new research. Dr. Schmeler added: “The bottom line is that this could really potentially simplify how we screen women and have it be more effective and not quite as complicated and burdensome — and opens the door for doing just HPV testing, which is actually what’s currently recommended by the World Health Organization for countries that don’t have Pap testing capabilities,”

Comments by Dr. Stewart Massad

Dr. L. Stewart Massad Jr. is a professor of obstetrics and gynecology in the division of gynecologic oncology at Washington University School of Medicine. He wrote an editorial to the study in the JAMA. He wrote: “What will replace the Pap test? In 2012, the American Cancer Society endorsed co-testing with cervical cytology testing and HPV testing at 5-year intervals as the preferred strategy for screening women 30 to 65 years of age because this approach combines the sensitivity of HPV testing with the familiarity of traditional Pap testing,” He then went on to say: “However, the addition of cervical cytology testing adds little to the accuracy of HPV testing while increasing cost and false-positive results. In 2018, organizations that develop cancer screening guidelines are wrestling with whether to recommend replacing co-testing with primary HPV testing as the optimal screening strategy.”

Future dilemma

In view of all those comments the regulatory agents will have to come up with solutions for what is in the best interest of women for testing for cervical cancer.

HPV Testing For Cervical Cancer

HPV Testing For Cervical Cancer

Conclusion

A large randomized clinical trial in Vancouver, BC, Canada has compared screening methods for cancer of the cervix in women. Half of the subjects underwent screening by the newer HPV tests that checks for the presence of HPV virus. The other half received conventional screening by the Pap test (a cytological screening test.) The result was that the HPV test was more sensitive and resulted in less early cancer tests 4 years down the road. With the conventional Pap test there were more than double the amount of abnormal cells present 4 years down the road, which makes the Pap test less safe compared to the HPV test.

It appears from this trial that the Pap test is no longer a choice, except for colposcopy procedures that take care of early cervical cancers. But for screening in general HPV testing every 4 years is all what every women needs for her protection.

Modified Poliovirus Effective Against Brain Cancer

A clinical trial found modified poliovirus effective against brain cancer. 61 patients with glioblastoma, the most deadly brain cancer there is, have been enrolled in this trial since 2012.

Glioblastoma treatment with genetically modified poliovirus

Dr. Gromeier, one of the lead cancer researchers at Duke University, Durham, North Carolina has done animal experiments. Unlike poliovirus, he found that genetically modified poliovirus was harmless for the central nervous system and yet he found modified poliovirus effective against brain cancer. This genetically modified poliovirus was attacking glioblastoma cells in cell cultures and in human brains. Dr. Annick Desjardins, a co-author of the study explained that the researchers had to take a piece of RNA away from the poliovirus and replace it with a neutral piece of RNA. This way it is still attracted to the numerous poliovirus receptors, which are expressed on many human cancers. The genetic sequence that allows poliovirus to reproduce in normal cells was taken out with the genetic modification. An inert RNA piece from the rhinovirus, the cause of the common cold was replacing this.

Effect of the genetically modified poliovirus

This way the modified poliovirus is no longer destroying nervous tissue. But the virus can still multiply in the glioblastoma cells, release toxins and kill these cancer cells.

Dr. Bryan Choi is a fellow in the Cellular Immunotherapy Program at Massachusetts General Hospital Cancer Center. He also works at the Department of Neurosurgery at Harvard Medical School. Although he was not part of this study he stated that this study was a giant step forward. “Perhaps the most promising aspect is the ability for this genetically modified virus to not only directly kill brain cancer cells, but to release tumor antigens,” Choi said. Antigens are toxic substances that stimulate the immune system to mount an immune response against the cancer. This immunotherapeutic effect is an important aspect of this new treatment modality.

Some human statistics of the pilot study showing modified poliovirus effective against brain cancer

Here are the highlights.

  1. 21% of the poliovirus patients are still alive three years after treatment; this compares to just 4% of the control patients who only received chemotherapy.
  2. The average survival time for the 61 patients who have received the genetically modified poliovirus therapy was 12.5 months. This compares with 11.3 months for a control group of matched patients. These had received standard treatment (chemotherapy).
  3. Some patients were much better responders than others. A 20-year old man a 60-year-old man survived 69 months (nearly 6 years). They are still alive today. This was unthinkable of in the past for patients with glioblastoma.

Repeat modified poliovirus therapy for glioblastoma recurrence

Dr. Darell D. Bigner, a co-author of the study, a professor of pathology and emeritus director observed the following. Some patients experienced initial reduction of the glioblastoma, and when the cancer came back they received repeat modified poliovirus treatments. To the surprise of the investigators the tumors shrank again and again. This was never the case with conventional chemotherapy. Once a glioblastoma is chemotherapy-resistant, chemotherapy will not work again.

Experience with modified poliovirus therapy

  1. In this trial treatment for glioblastoma started with implanting a catheter right into the center of the glioblastoma. An infusion of the engineered poliovirus followed, a process that could take up to 6.5 hours. Removal of the catheter was next.
  2. In the beginning researchers used higher doses of the genetically engineered poliovirus. Some people developed severe inflammation causing seizures, which needed treatment. Confusion and language difficulties were also side effects. Others developed pronounced nausea. The researchers decided to lower the dosage of the genetically engineered poliovirus, and the patients still had good clinical results.
  3. “We are presently enrolling in a phase 2 trial combining the genetically modified poliovirus with one dose of chemotherapy,” Desjardins said. “We are also enrolling in a trial for pediatric brain tumor patients.” In addition studies using genetically engineered poliovirus against breast cancer and against skin cancer are also in the planning stage.
  4. There are other new approaches where there the doctor injects the photosensitizer indocyanine into breast cancer tissue. Next the doctor points a laser beam near the infrared frequency of light to the cancer area. You find details about this procedure here.
Modified Poliovirus Effective Against Brain Cancer

Modified Poliovirus Effective Against Brain Cancer

Conclusion

A new approach to treating glioblastoma, one of the deadliest brain cancers, has shown promising results. A genetically engineered poliovirus is no longer making the person sick with polio, but instead destroys glioblastoma cells and prolongs patients’ lives. Some patients lived up to 6 years while controls lived less than one year. The effect of this new treatment occurs from the release of toxins within the glioblastoma cancer. This leads to cancer cell death and the release of these toxins. The immune system receives stimulation to recognize and destroy the remaining glioblastoma cells. At this point the basic steps of this new therapy are in place.

Future direction of research

But the same method will one day likely be in use for other cancers. There are plans for new clinical trials to examine this further. The researchers also want to test cure rates of a combination of chemotherapy and genetically engineered poliovirus therapy. This will answer the question whether the combination treatment will be better than genetically engineered poliovirus therapy alone.

Frequent Flying Can Increase Cancer Rates

A review article from June 25, 2018 discusses that frequent flying can increase cancer rates. A study showed that cancer of the breast, cervix, skin, thyroid and uterus are about twice as common in female stewardesses than in women at large. Also, gastrointestinal system cancers including cancer of the colon, stomach, esophagus, liver and pancreatic cancers are more common. This observation was true in both male and female flying personnel who engage in frequent flying. This publication comes from a scientific paper published on June 26, 2018.

Study of flight attendants

Patients from the National Health and Nutrition Examination Survey (NHANES) served as a control for flight attendants. This control group consisted of 2729 patients; they were of a similar socioeconomic status as the flight attendants. In contrast there were 5366 flight attendants with much higher cancer rates than normally expected. Specifically breast cancer had a 1.51-fold higher frequency than the control group. Melanoma had a frequency of 2.27-fold in comparison to controls, and non-melanoma cancers had a cancer rate of 4.09-fold when compared to controls. Non-melanoma cancer cases include basal cell and squamous cell carcinomas.

Cancer rates in pilots

In a meta-analysis of various studies it became obvious that pilots had 20% more prostate cancer than a non-pilot control group. However their mortality was not higher than controls.

In an interesting study spanning over 60 years Icelandic airline pilots underwent an analysis for cancer development.

83 cancers were registered. The general population (non-pilots) served as controls.  There was an increase of 2.42-fold for all cancers compared to controls. Prostate cancer was higher in these pilots by 2.57-fold. Malignant melanoma had a 9.88-fold increase in pilots in comparison to controls. The basal cell carcinomas in these pilots were 3.61-fold more common than the rates in the controls. With regard to basal cell carcinomas of the trunk there were 6.65-fold more of them in comparison to controls.

The difference between the pilots and the general population was likely due to the higher exposure to cosmic radiation. This is what the authors concluded.

How does cancer develop?

There are several ways cancer can develop. One of the known cancer causations is ionizing radiation. We know a lot about this from the atom bombs of WWII in Japan. There were many more thyroid cancers in children than were normal following the dropping of the atom bombs.

But diagnostic CT scans and X-rays are not without risk of cancer development either. There is a lag period of 10 to 20 years and even longer. But after this time the higher cancer rate becomes measurable. A person who had a CT scan done as a diagnostic test in childhood will still have a 25% higher cancer rate 15 years later. This is how powerful radiation of the DNA of our cells is despite inherent repair mechanisms that fight back to keep things normal.

Single cancers versus multiple cancers

It is interesting that female stewardesses and male pilots came down with a mix of various cancers. There were skin cancers, breast cancers, cancers of the prostate and many gastrointestinal cancers. The numbers were not big enough to show statistical significance for leukemia also being a likely cause of cancer from cosmic radiation.

If cosmic radiation was going through the body randomly hitting various DNA strands in all cell types, which could explain why a random number of cancers develop in those cells that got the highest exposure. The ones who got above average cancer were stewardesses and pilots who were longest on their jobs. A variety of cancers would develop from various tissues. This is exactly what the studies have shown.

There are frequent flyers like business travelers and vacation seeking retirees who will also be at a higher risk of developing cancer. The more they fly, the higher the risk.

Other causes of cancer

Cosmic radiation is only one cause of cancer. There are many other causes of cancer. If you smoke heavily or abuse alcohol this can cause genetic mutations of cells that can develop into cancer. There is a pathway to cancer, which consists of initiation, promotion and progression. After those initial hurdles the cancer cell will multiply and start metastasizing into other areas of the body.

Carcinogens can damage the DNA of cells. In the case of pollution carcinogens enter the body through the air. But consuming processed meat and red meat has a proven link to cancer development as well, namely colon cancer.

Diverse factors all can cause cancer

Chronic inflammation from chronic infections is also carcinogenic. Chronic gastritis is caused by H. pylori. After years of infection with this pathogen stomach cancer can develop. Hepatitis viruses that are chronically present in liver cells can be the cause of liver cancer. Human papilloma virus (HPV) is the cause for the development of cancer of the cervix. The majority of cancer is caused from the environment or by poor life styles. Only 5 to 10% of cancers are inherited.

Tumor suppressor genes are important in terms of resisting the development of cancer. The TP53 gene produces a protein that interferes with the multiplication of cancer cells. Cancer cells in turn can produce a protein that interferes with TP53 function. The end result is that it will interfere with the body’s immune system to produce killer T cells. This way the cancer has the upper hand. There are some herbs that have shown anti-cancer effects, such as curcumin. http://www.askdrray.com/curcumin-and-cancer/. As I explain in this blog, there are absorption problems with curcumin presently. It is not yet primetime for curcumin, but it could be once the absorption problems are overcome. Nevertheless the research surrounding curcumin is interesting.

Frequent Flying Can Increase Cancer Rates

Frequent Flying Can Increase Cancer Rates

Conclusion

Several interesting studies have shown that stewardesses, pilots and frequent airplane travellers have a higher risk of developing cancer. Research groups have been careful to control these studies for lifestyle factors and other causes of cancer. Exposure to cosmic radiation is the common culprit that is behind this cancer causation. There was a multitude of cancers rather than one single type of cancer in pilots and stewardesses. This makes it more plausible that it is indeed cosmic radiation that caused the cancer increase. But cancer development is complex, and I have summarized this briefly here. It is important to be aware of all the possible causes of cancer. This allows you to minimize your exposure to carcinogens. We all get exposure to carcinogens from pollution. In addition we get exposure to cosmic radiation according to how much time we spend flying to holiday destinations or on business trips. Be safe and be informed!

Less Chemotherapy For Breast Cancer Patients

A new clinical trial suggests that less chemotherapy for breast cancer patients is necessary than what is the custom today.

70% of the common form of breast cancer, which is estrogen positive, but HER2 negative (more info below) has received treatment with surgery and subsequent chemotherapy. However, there was no scientific basis for this and this is what this large clinical trial was all about. The trial is discussed under this link. It has its origin in a medical research paper in the New England Journal of Medicine.

Estrogen positive, HER-2 negative breast cancer

The majority of breast cancers belong into this category. They have no signs of metastases and the Oncotype DX Breast Recurrence Score test has a score between 0 and 10. A woman with breast cancer like this does not need to undergo chemotherapy, because her long-term survival will not be any better on chemotherapy, and she can save all of the complications of chemotherapy.

The Oncotype DX Breast Recurrence Score

With this relatively new test 21 genes are tested in breast tissue from biopsies and surgical specimens. Dr. Otis Brawley, chief medical and scientific officer for the American Cancer Society, who was not part of the study explained: “What that test does is look at 21 different genes to see if each is turned on or off and then if it is over-expressed or not. So we have two yes-no answers for each gene. It looks at all 21 of those answers and gives that cancer a recurrent score between 0 and 100.” This number based on genetic cancer markers determines how likely the breast cancer is to reoccur in the next 10 years.

Relevance of genetic score test

A low score of between 0 and 10 on this test is indicative of good long-term survival. These patients will not need any chemotherapy. A medium score of 11 to 25 also has good survival as in this trial. However, scores of over 25 have an association with poor outcomes, when the patient receives only hormone therapy. In these cases the researchers say chemotherapy is also necessary in addition to hormone therapy.

Clinical trial regarding whether or not chemotherapy is necessary in the intermediate risk breast cancer patient

10,273 women were part of this trial between April 7, 2006, and October 6, 2010. 6,711 had test scores between 11 and 25, which placed them in the intermediate risk. Half of them received hormone therapy and chemotherapy. The other half received hormone therapy only. After an average of 9 years 83.3% of those on hormone therapy alone did not develop a recurrence of breast cancer. They also did not develop a second cancer. For the other group on both hormone and chemotherapy the rate was 84.3%. The difference between the two was not statistically significant. This established that the intermediate risk breast cancer patient does NOT require chemotherapy.

Results of clinical trial a surprise

This was a big surprise. Oncologists always included chemotherapy in the routine treatment schedule for these patients. But the trial clearly showed that hormone therapy alone was good enough! This allows thousands of breast cancer patients to avoid the devastating side effects of chemotherapy. Why would a woman undergo unnecessary chemotherapy, loose her hair, vomit and get stomach upsets? She may also suffer osteoporosis and undergo bone marrow suppression, which makes her more prone to serious infections.

Premenopausal women and those younger than 50 

There is a group of women where breast cancer is more aggressive. Research followed this subgroup of women (premenopausal women and women below the age of 50) separately in the trial. More deaths occurred in the group that received hormone therapy alone. But death rates were much lower with a combination of hormone therapy and chemotherapy. If the score in these women was 16 or higher these women should receive the regular treatment consisting of surgery and hormonal measure). But they should also receive chemotherapy at the same time to reduce complications from their breast cancers. It has been known for many years that breast cancer in this particular patient group has a more aggressive growing habit. This trial showed that survival was a lot better in the group that did receive chemotherapy as well.

Surface markers of breast cancer

1. BRCA1 and BRCA 2

BRCA1 and BRCA 2 are rare mutations in some women who get early breast cancer, often on both breasts and often ovarian cancer as well. These are women who benefit from bilateral mastectomies, even when there is no cancer present yet.

2. HER2

HER2 is a protein that is expressed on the cell surface of some breast cancers. It leads to faster cell proliferation. Only about 30% of all breast cancers are HER2 positive. They respond to Herceptin and other medications listed in this link. In the past the prognosis for HER2 breast cancer was poor, now with better medication against this condition it has one of the more favorable outcomes.

3. ER and PR surface receptors

Estrogen receptor (ER) positive cancer cells will lead to faster tumor growth, when the patient receives estrogen. It also grows faster under the influence of estrogen or progesterone. About 65% of all breast cancers are hormone receptor positive (ER or PR). They will respond to drugs like Tamoxifen and others.(See this link)

Less Chemotherapy For Breast Cancer Patients

Less Chemotherapy For Breast Cancer Patients

Conclusion

Breast cancer diagnosis and treatment is rapidly changing. A clinical trial from the New England Journal of Medicine with over 10,000 women with breast cancer showed the following:

It is safe to treat women with an intermediate risk of breast cancer with surgery of the primary cancer and follow this up with hormone therapy. In the past these women were undergoing chemotherapy in addition, which has not shown better survival rates. On the other hand, premenopausal women or women below the age of 50 should receive treatment with chemotherapy to improve their long-term survival. Other factors to consider are the hormone receptors (ER and PR) and the HER2 marker. The Oncotype DX Breast Recurrence Score test has added a completely new dimension to breast cancer treatment as the New England Journal of Medicine article has shown. Overall breast cancer treatment has improved, which is good news for women.

Writing A Medical Book

In my 40’s when I was practicing medicine, I was dreaming about writing a medical book. This was in the mid 1980’s and I was busy seeing 30 to 40 patients a day. I would never have found the time to write a medical book at that time. I thought, perhaps I could show how patients could stay younger for longer by adopting the right life style in order to stay well. Fast forward 3 decades, and the medical book writing began. But instead of one book the project turned into 4 books. There were too many topics to cover to fit them all in one book.

Prior to writing a medical book

First of all, in 2002 I published a large website. Its structure is like a book on the Internet: Net Health Book . It contains descriptions of the major diseases, mental and physical, and their current treatment modalities. I still maintain this work. Furthermore, I started another website in 2003, a weekly blog, called “Ask Dr. Ray” . This is a compilation of interesting research. Some medical research papers can get too scientific. For this reason I translated it into easier language. The topics tend to be anti-aging topics. This blog comes out Saturdays.

Retirement hobby

When I retired in 2010 I revamped my websites. In the process the web developer suggested I should add to Net Health Book a blog (nethealthbook.com/news) where I review current health news that I find interesting. This is a weekly blog, which I publish on Wednesdays. All of this is still going on, and it gave me lots of opportunities to write and publish on a smaller scale. In addition, I finally started publishing books.

A Survivor’s Guide To Successful Aging

My first book came out with Amazon in 2014. I had joined the A4M (American Academy of Anti-Aging Medicine) in the early 2000’s. The lectures at their conferences were very open-minded and pointed out details of what one could do to delay aging and avoid premature deaths. My own experience with changing our diet in 2001, starting bioidentical hormone replacement and changing my lifestyle became topics that were part of this book. I dedicated this book “to those who are willing to work on prevention in order to achieve a longer life without disabilities”. This is still the basis of prolonging your life.

Lifestyles can be deleterious

I start out in this book describing the obesity wave and how this changes the metabolism (metabolic syndrome). I used statistics from the Framingham Heart Study to show the detrimental effects of various lifestyles on mortality. Subsequent chapters deal with food, exercise, stress and missing hormones as life-shortening factors. There is a separate chapter on vitamins and supplements. They as a group can create 5.1% longer telomeres, which translated into 9.8 years of longer life expectancy (see also a study by Dr. Xu  in the book). Subsequently it describes how a change of your lifestyle can have a positive impact. Changing your eating habits and exercise activity will make a tremendous positive difference on the long term.

Successful Aging in the Kitchen

The book ends with an appendix, written by my wife: “Successful Aging in the Kitchen”. You are presented with recipes for 7 breakfasts, 7 lunches and 7 dinners. In addition she has provided 7 healthy desserts for you. Bon Appétit!

Healing Gone Wrong, Healing Done Right

In another book, which got appeared in 2016 I gave a few examples of how famous people were failed by medicine. It started already in the past: Ludwig van Beethoven’s physicians did harm instead of healing their patient. However, this is happening now as well: physicians mismanaged the health care of Elvis Presley, Churchill, Michael Jackson and JF Kennedy. The physicians treated symptoms, but they never properly attended to the causes of the ailments of their patients. The end result was premature death in all of them. Churchill who had good genetics made it to age 90, but during his last 15 years he suffered of severe disabilities.

Treatment of symptoms will fail, treatment of causes succeed

These examples of famous people’s health problems resemble to what happens to today’s patients in various office settings. Their symptoms are mostly being treated, but their causes often not. Simply treating symptoms will not work on the long term. It did not work in the past, and it does not work now.

Other chapters in this book

Other chapters in this book deal with preventing disease, keeping a healthy brain and keeping a healthy heart. Next I discuss why food matters, followed by the health of limbs and joints. Subsequently I am discussing how to keep toxins out. The next chapter deals with how to reduce the impact of cancer. It is always important to diagnose cancer as early as possible as removal by surgery has the highest success rate at an early cancer stage. The next chapter is entitled: “Stable hormones key to health”. If any of your hormones are missing (particularly around the age of menopause and/or andropause) it is time for nature identical hormone replacement. The next chapter gives you general thoughts on anti-aging. This is followed by “supplements yes, but do not overdo it”.

Alternative treatment for ADHD

A final chapter gives you an example of an alternative treatment for ADHD, where the idea of not just treating symptomatically, but treating causes is included. References and an index are also provided for the book.

Prostate Cancer Unmasked

Furthermore, I did not intend to write this book. But in early 2016 my PSA (prostate specific antigen) level jumped from 3 to 8.6. For years it had been in the 1.5 areas, then slowly increased to 3. But 8.6 was too high for comfort! I had an MRI scan done, which showed one lesion in my left prostate, which was suspicious for prostate cancer. I was referred to a urologist at the Vancouver Prostate Centre, one of the top clinics in Canada. But I had already researched the literature and came across research by Dr. Gary Onik from Ft. Lauderdale who warned me about the pitfalls of “standard therapy”.

The conservative urologist in Vancouver

The urologist in Vancouver told me that without a positive biopsy he cannot accept that the shadow on my MRI scan would be prostate cancer. And the only way they do a prostate biopsy was by random trans-rectal biopsies. He also wanted to include me in a random clinical trial where they would compare active intervention with active surveillance. I politely declined the trans-rectal prostate biopsy and the inclusion into a trial.

Assessment by Dr. Onik

I booked a flight to see Dr. Onik in Ft. Lauderdale. His method is well researched and orchestrated.

Initial assessment

He assesses you with a rectal ultrasound and he sees the prostate on a TV screen. He said right away that I had three separate lesions, one in the left as shown on the MRI scan and two in the right lobe, which was missed by the MRI scan. False negative lesions are common on MRI scans, which can become a source of cancer recurrence.

3-dimensional prostate biopsy

The following day he booked me for a 3-dimensional prostate biopsy via the perineal approach. The perineum is easy to sterilize, so there is no risk of septicemia. A metal grid with holes for biopsy needles was used to get 96 biopsies of my enlarged prostate. For a normal size prostate, Dr. Onik said about 60 biopsy needles are normal. You don’t feel anything, because you are asleep.

Cryoablation prostate surgery

Next was the cryoablation surgery of the 3 prostate cancer lesions. This happened one month after the biopsy. I was seen at the hospital in Ft. Lauderdale. The same grid from the biopsy was used to relocate exactly where the cancer lesions were. The pathologist had confirmed them as Gleason 6 and 7 prostate cancers. This was treated with Argon sounds and frozen twice. I felt nothing, because I was under a general anesthetic. But Dr. Onik told me that everything went very well. Some cancer was too close to the neurovascular bundle, so he used the NanoKnife, an invention where nano-size holes get blasted into cancer cells, but it leaves normal tissue intact.

I needed to do self-catheterization for about one month to empty my bladder, as there was a lot of swelling from the prostate hypertrophy and the surgery. But eventually my normal water works returned.

Follow-up blood work

My follow-up PSA blood work 3 months after the surgery was down to 1.0. Prior to the surgery the Oncoblot test was positive for prostate cancer. A repeat Oncoblot test 3 months after the surgery was now negative for prostate cancer. I realize that not every physician accepts this new cancer-screening test, but I felt a lot better to know that all the cancer markers were now gone.

9 cancer treatments reviewed

In my book I described a total of 9 prostate cancer treatments and their 10-year survival statistics. None of the other treatment methods were as good as Dr. Onik’s statistics. I believe it is linked to the precision of the 3-dimensional biopsy and the surgery being done through the same grid. If you do not perform the surgery this way, you miss cancer lesions and this becomes the source of failure 10 years down the road. My book details all these alternative treatments. It also has a section on lifestyle modifying factors. I needed to write this book as a service to any man who suddenly is faced with a possible diagnosis of prostate cancer.

Unmasking prostate cancer

Like me he needs to unmask the cancer. Is it really there? How far advanced is it? Which way to safely biopsy it (definitely NOT through the rectum for fear of blood poisoning=septicemia)? What is the best method to remove it? I came to the conclusion that Dr. Onik’s method was best for me. But with the information in this book you can decide what is best for you.

Medical Questions Answered

Finally I wrote my 4th book. From more than 4400 medical questions that I have answered on the site Quora.com I selected the most popular questions for this book. The editorial board of Quora said that I own the publishing rights for my answers. The questions were rephrased without changing the meaning. I selected more than 120 questions under 44 different headings.

Here are some of the areas that are covered: Acne, the best home remedies. Aging: can it be reversed? What is the limit for a human? Alcohol: how does it affect your body? Alzheimer’s disease: which foods promote brain health? Arthritis: what can you do about osteoarthritis? Back pain: what can I do about it? Cancer: why can cancer still not be cured? There are as well 15 other answers about cancer. Depression: will my depression ever go away? Diabetes: will a 600-calorie diet help diabetes control?

Further topics discussed

Diet: I want to get rid of sugar in my diet. How can I do this long-term? Other answers about diet are included. Exercise: How useful is cardiovascular exercise? Gut disease: Is “gluten free” food healthy? Heart disease: What can I do to clean out my arteries and reduce my risk for heart disease? Hormones: Is estrogen present in the male body? Life Expectancy: What is the theoretical life expectancy of humans? Lifestyle Habits: Can good habits change your life completely? Pain: Pain relief for a headache or other pain: Aleve, Advil or Tylenol? Pregnancy: Best age for a successful pregnancy? Prostate Cancer: How dangerous is prostate cancer? Does it kill you? Schizophrenia: What complementary approach may help a patient with schizophrenia? Sleep: What happens when you go to bed late every night? And many other answers under this topic.

And the book finishes with these topics

Sugar: will I be OK living without sugar? Vaccinations: Is there a connection between vaccinations and autism? Vitamins and supplements: Are taking vitamins and supplements healthy or are they harmful? Weight loss: I am working out every day, but I am not loosing weight. What should I do? There are many more answers under this topic. Younger for longer: What are three things I can do every day to stay younger for longer?

These are only a few selections of all of the topics dealt with in this book.

Conclusion

I have reviewed briefly why I published the books mentioned above. My prostate cancer book developed out of the necessity that I had to deal with my newly diagnosed prostate cancer in 2016. I felt that the review process I went through would be good for those men who have to face a similar situation. The anti-aging book comes from my interest in anti-aging medicine. “Healing Gone Wrong, Healing Done Right” developed from the observation that physicians in the past and often even now tend to only treat symptoms. But if a cause can be found, this should be treated, as this often leads to a permanent cure.

Treating symptoms only will not improve the patient’s condition

Treating symptoms only will not improve the patient’s condition. “Medical Questions Answered” is a collection of medical topics where I answered various medical questions. It was a way for me to cover a vast array of medical topics. Some of the topics are dealt with in depth (acne for instance); others are very short. I have also two medical blogs that come out on Wednesdays and Saturdays. I hope that some of that medical information will be useful to you.
