Soy Does Not Appear To Increase Breast Cancer Deaths, Recurrence, Study Finds

Being fat does.

"Soy foods may not be harmful to breast cancer survivors -- as some animal studies have suggested -- and they could even reduce the risk of recurrence of the disease, according to a study in the Journal of the American Medical Association, the Los Angeles Times reports. Breast cancer survivors have previously been told to avoid soy products in light of animal research showing that soy might increase the odds of a recurrence of the disease. Researchers had believed soy acts like the hormone estrogen, which promotes breast tumor growth.
The new study of more than 5,000 breast cancer survivors in China found that women who had the highest soy intake had a 29% lower risk of dying during the study period and a 32% lower risk of breast cancer recurrence than the women who had the lowest intake."
