Weight Loss and Risk Reduction
This is a short article from Health Day about a recent study suggesting the weight loss, even 5% of body weight, reduced by as much as half the risk of developing estrogen positive (ER positive) breast cancers. Although this research was directed at women who had not been diagnosed, it is not a huge leap (at least for us non scientists) to wonder if the same thing might be true for reducing recurrence risk. Since we all know, and I have been hammering it in, that exercise and weight maintenance, if not actual loss, seem to reduce recurrence risk, this is another piece of information that helps us understand the possible reasons.

Dieting May Lower Hormone Levels Tied to Breast Cancer
Study didn't prove that weight loss lowers risk, but it did cut estrogen, which may help older women
MONDAY, May 21 (HealthDay News) -- New research suggests that weight loss through exercise and dieting helps overweight women lower the levels of certain hormones in their blood, potentially raising the odds that they'll avoid developing breast cancer.
The findings don't prove that losing weight this way will prevent breast cancer. Still, women who take medications to prevent the disease "need long-term solutions for managing their risk," study co-author Dr. Anne McTiernan, director of the Prevention Center at the Fred Hutchinson Cancer Research Center, said in a news release from the center.
"Weight loss represents an additional option for long-term breast cancer risk reduction without significant or bothersome side effects," McTiernan added.
