4 Steps to Take Now to Lower Your Breast Cancer Risk

By Deborah Kotz

Posted: September 3, 2009

New research out this week from the American Institute for Cancer Research adds to the growing body of knowledge about actions women can take to lower their breast cancer risk. The new report is an update of previous research, adding results of 81 new studies to the findings of more than 800 that have followed women in the United States and around the world to see who develops breast cancer and who doesn't. The study authors contend that some 70,000 cases of breast cancer—representing 40 percent of new U.S. cases—could be prevented every year if women followed these measures.

I'm always a little hesitant to report about research that lowers your cancer risk. Leading breast surgeon Susan Love, author of Dr. Susan Love's Breast Book, has told me time and time again that the vast majority of breast cancers—the ones not triggered by an inherited gene mutation—have no known cause. And it's tough to tease out particular lifestyle habits that protect us from cancer since women who, say, exercise a lot may be more health conscious in general, eating better and seeing their doctor more often than those who don't. What's more, I think such research inadvertently conveys the message that people are somehow to blame for their cancers. With the exception of smoking and lung cancer, that's simply not the case. (And there are plenty of folks who develop lung cancer and never smoked a day in their life.)

Still, there are some very concrete things we can do to maximize our odds of thwarting breast cancer. "We're not blaming the victim," study leader Susan Higginbotham said on an MSNBC interview posted on the AICR Web site. Rather, she says the study provides good news for women, things they can do to protect themselves. They are the following:

1. Be as lean as possible without being underweight. A healthy body mass index is defined as being above 18.5 but no greater than 25; that's equivalent to a weight range of 105 to 142 pounds for a 5-foot 4-inch woman. Studies have shown, though, that women closer to the lower end of the healthy weight range have the most protection from breast cancer.

2. Exercise for at least 30 minutes a day. Higgenbotham says if you can't do that, do less. Some activity is better than none, but the more, the better.

3. Limit alcohol consumption. If you drink at all, limit your intake to one serving a day—a glass of wine (5 ounces), shot of liquor (1.5 ounces), or bottle of beer (12 ounces).

4. Breast-feed. New mothers should breast-feed exclusively for up to six months since the AICR says "evidence is convincing that mothers who breast-feed reduce their risk for breast cancer." Breast-feeding may also lower the child's risk of obesity later in life.

Research tells us breast cancer is an environmental disease

It would be helpful if Dr. Susan Love looked about more.

Two years ago, the Susan G. Komen organization and the Silent Spring Institute published “Environmental Factors in Breast Cancer,” described as the most comprehensive review to date of scientific research on environmental factors and breast cancer risk. Researchers concluded that environmental pollutants contribute by “damaging DNA, promoting tumor growth, or increasing susceptibility by altering mammary gland development.” Because breast cancer is so common and the chemicals so widespread, they said, "if even a small percentage is due to preventable environmental factors, modifying these factors would spare thousands of women. Regulators have not paid much attention to potential mammary carcinogens.” The study concluded that cancer is an environmental disease.

Because this conclusion conflicts with so many of SGK's sponsors, the organization virtually buried the report. A public education campaign to prevent cancer was never launched.

SGK advocates annual mammograms. Thus they advocate an annual dose of radiation. As ABC News pointed out 9-1-09, up to 75 percent of biopsies performed as a result of mammogram findings reveal benign conditions. In the U.S. alone, it is estimated that the cumulative risk for a false positive result after 10 mammograms is nearly 50 percent.

SGK would do much better to advocate thermography - but that would run afoul of their sponsors as well. Thus they turn a blind eye to modern day thermography, the technology that can often detect cancers ten years earlier than mammography.

One of SGK's million dollar sponsors is M&M candies. Otto Warburg won the Nobel Prize in the 1930s by demonstrating that cancer cells use much more sugar than normal cells. In fact, PET scans are based on this principal. Because the cancer cells take up the sugar so much faster than normal cells, the radioactive agent is delivered with a sugar solution. And yet SGK promotes candy...

In the grocery store this week, I saw a large display of items with the pink ribbon. Among the items was a brand name air freshener. These products are full of VOCs regulated as either toxic or hazardous.

In 2008, Donna Jackson Nakazawa wrote "The Autoimmune Epidemic" and it was endorsed on the back jacket by leaders at John Hopkins and NIH. She documents that a woman is 8 more times likely to come down with an autoimmune disease than breast cancer. SGK collects a lot of money and has little to show for it. Let's shift our focus, shall we?

We know the majority of American women (and children) are deficient in vitamin D and that it is protective against cancer - it increases the self-destruction of mutated cells. One recent study showed that calcitrol (the active form of vitamin D) can induce a tumor-suppressing protein that inhibits the growth of breast cancer cells specifically.

Please look elsewhere than Dr. Love for answers.

Cancer Prevention

Why doesn't anyone in the media talk about vitamin D to reduce the risk of cancer? Studies show that the cancer rate would fall by as much as 70 percent if everyone had optimal levels of vitamin D in their blood. SEVENTY PERCENT!!!

Studies also show that about two-thirds of all Americans are deficient in this vitamin. Where's the outrage?
