Up to a Third of Breast Cancer Cases could be Prevented

EcoHealth & Wellness would like to share some of the recent research that has come out regarding treatments with breast cancers.  Doctors are now saying that by eating less and exercising more 1/3 of the new breast cancer cases can actually be avoided.  Early detection by screening is still advantageous if you have a family history, but many doctors agree that the screening technology is as advanced as it can be right now.  But what we can control as an individual is our lifestyle.

A woman’s lifetime chance of getting breast cancer is about one in eight. Obese women are up to 60 percent more likely to develop any cancer than normal-weight women, according to a 2006 study by British researchers.

Many breast cancers are fueled by estrogen, a hormone produced in fat tissue. So experts suspect that the fatter a woman is, the more estrogen she’s likely to produce, which could in turn fuel breast cancer. Even in slim women, experts believe exercise can help reduce the cancer risk by converting more fat into muscle.

The American Cancer Society Web site says the connection between weight and cancer risk is complex. It says risk appears to increase for women who gain weight as adults, but not for women who have been overweight since childhood. The cancer society recommends 45 to 60 minutes of physical activity five or more days a week to reduce the risk of breast cancer.

Drinking less alcohol might also help. Experts estimate that having more than a couple of drinks a day can boost the risk of breast cancer by 4 to 10 percent.

After studies several years ago linked hormone-replacement therapy to cancer, millions of women abandoned the treatment, leading to a sharp drop in breast cancer rates. Experts said a similar reduction might be seen if women ate healthier and exercised more.

Holmes, the Harvard expert, said changing diet and nutrition is arguably easier than tackling other breast cancer risk factors.

In the 1980s and 1990s, breast cancer rates steadily increased, paralleling a rise in obesity and the use of estrogen-containing hormones after menopause.

La Vecchia said countries like Italy and France — where obesity rates have been stable for the past two decades — show that weight can be controlled at a population level.

“It’s hard to lose weight, but it’s not impossible,” he said. “The potential benefit of preventing cancer is worth it.”
