Conventional risk factors
Conventional doctors admit that they cannot explain the cause of 70% of breast cancers. Current medicine says that 30% of cancers can be explained (1, 2, 5) by the following risk factors:
- Age. The risk of breast cancer rises with age.
- Sex. 99% of cases of breast cancer occur in women.
- Hereditary / family history (5% of cases).
- Prior cancers.
- Not having children or having them after age 30 slightly raises the risk.
- Not breastfeeding. Studies have shown that breastfeeding slightly lowers breast cancer risk, especially if breastfeeding continues for at least 1.5-2 years.
- Early menarche or menopause.
- Recent use of birth control pills. Women who stopped using the pill more than 10 years previously do not seem to have any additional risk.
- Alcohol. Women who drink 2-5 drinks daily have about 1.5 times the risk of non-drinkers.
- Lack of sunlight causing Vitamin D deficiency. (9, 14, 15, 16). A study published in 2018 showed that women with good levels of vitamin D from sunlight were 80% less likely to have breast cancer. (16) Living indoors most of the time. Being exposed to artificial light, primarily in the blue spectrum, for large parts of the day. Get more sunlight. Get out in the sun, get lots of natural sunlight into your eyes and onto your skin all over your body for hours every day. Eat in the sunlight. Walk and exercise in the sunlight. If you are living in a high latitude and suffering badly from your illness, you may have to move to a location closer to the equator (less than 20 degrees latitude). To test how successful sunlight is, try to have your next holiday or vacation in a place close to the equator. Spend your days outdoors. Get up and out of bed so you can watch the sunrise. Do not wear sunglasses. Do not use sunscreens. Of course, take care not to get sunburned or even slightly red. (14, 15)
- Standard American Diet (SAD). Immigrants to USA who adopt the SAD suffer increasing rates of breast cancer compared to family who remain in the country of origin. America has the highest proportion of genetically modified foods of all countries. It also has the highest level of fructose added to most foods as HFCS, with the majority of the population now being sugar-addicted. Sugar is a direct and potent cause of cancer.
- Wrong fats. Throughout Grow Youthful I emphasise that polyunsaturated omega-6 oils (vegetable oils) are not found in nature, and cause cancers and many other degenerative illnesses. In contrast, saturated fats are healthy fats and protect against these diseases. Saturated animal fats are also valuable in creating a healthy cholesterol profile.
- Social factors. Isolation, lack of close friends, lack of family support. One study showed that breast cancer patients who increased their social support reduced their risk of dying by an amazing 70%. (10) It doesn't matter whether that support is obtained from one or two close friends, many friends, or a partner - the benefits are still there. (11)
- Obesity. (12)
- Exercise - lack of. (13)
- Hormonal factors. Phytoestrogens (xenoestrogens),
estrogen, insulin and
testosterone are associated with increasing cancer rates,
progesterone with lower rates. Factors which increase exposure to endogenous estrogens
and increase lifetime risk of developing breast cancer include not having children, delaying first childbirth, not breastfeeding, being overweight, (12) early menarche and late menopause. (5)
Hormonal replacement therapy (HRT) using synthetic proprietary hormones (rather than bio-identical hormones) substantially increases the risk of breast cancer.
Melatonin (7) is depleted through lack of deep sleep (on this page I explain how any light at night can cause melatonin level to plunge).
- Iodine deficiency.
- Radiation. Exposure to X-rays or radiation cancer treatment early in life, particularly during the teens. See 4G and 5G EMF radiation.
- Coffee may protect against breast cancer. (8)
- Brassica vegetables. Regular consumption of broccoli, cauliflower, cabbage and Brussels sprouts significantly lowers the risk of breast cancer.
- Mushrooms. Published studies (3, 4, 17) show that regular consumption of mushrooms can lower the risk of breast cancer by 50%. Women who consume both mushrooms and green tea have a 90% lower incidence of breast cancer.
- 3 out of 4 women who wore a bra for 24 hours per day developed breast cancer.
- 1 out of 7 women who wore bras more than 12 hour per day but not to bed developed breast cancer.
- 1 out of 152 women who wore their bras less than 12 hours per day got breast cancer.
- 1 out of 168 women who never or rarely wore bras got breast cancer.
The more important risk factors
Bra risk factor
Bras may be a risk factor for breast cancer. Surprisingly, the conventional medical list of risk factors does not consider what to me is an obvious candidate - the wearing of a bra for long periods each day. There are certain points around the body where the wearing of tight clothing may constrain the flow of the lymphatic system, and a bra around the breasts is the most susceptible point of all.
It could be that bras are the risk main factor for breast cancer along with lack of regular sunlight on the skin and in the eyes, and the daily consumption of sugar. The bra factor needs further research, but unfortunately it tends to attract derision rather than research funds.
Sydney Ross Singer and Soma Grismaijer argue in their book (6) that bra-wearing may be a major cause of breast cancer. They explain that constriction from tightly worn bras inhibits circulation in the lymphatic system. This stops the removal of waste and toxins, and leads to a build-up of fluid within the breast tissue. Carcinogenic toxins that we take into our bodies through polluted food, air and water remain in the body, particularly in the lymphatic system. A tight-fitting bra, according to the authors, concentrates these toxins within the breast tissue, which is near the lymphatic system's outlet into the bloodstream. They show how there is a high correlation between the use of bras, and breast cancer.
Singer and Grismaijer claim that breast cancer is only a problem in cultures where women wear bras; in bra-free cultures breast cancer is rare. They maintain that women who wear a bra 24 hours a day are 125 times more likely to get breast cancer than women who are bra-free. Their study also claims that bra-free women have about the same incidence of breast cancer as men.
This husband and wife team examined the bra wearing attitudes and behaviours of over 4,700 women in 5 major US cities, about half whom had had breast cancer. Those who had had breast cancer were asked about their bra-wearing habits prior to their diagnosis of cancer. Although the authors did not adhere to the scientific protocols required for a medical study, they hoped that the medical industry would follow-up with further research to either verify or refute their findings. Their study findings were:
Unfortunately, the medical and pharmaceutical industries rejected their findings out of hand. The pharmaceutical companies and their shills, and many doctors and researchers who are entrenched in their positions, sneer that wearing a hat or shoes is also a constriction on the body. They miss the point that these are not major lymphatic flow points or lymphatic nodes. The authors attributed this rejection to the greed of the fashion and medical industries: "The bra industry is a multi-billion dollar enterprise. And billions of dollars are spent each year researching and treating breast cancer. Ironically, ending breast cancer could cause financial hardship for many people."
