Dietary Soy Does Not Cause Uterine Cancer
Studies in monkeys and women suggest that unlike traditional estrogen therapy, a diet high in the natural plant estrogens found in soy does not increase the risk of uterine cancer in postmenopausal women. In contrast, soy may have a protective effect.
These findings are from a series of studies led by Mark Cline, DVM, PhD, an associate professor of comparative medicine at Wake Forest University Baptist Medical Center.
Dr. Cline notes that the results of these studies apply to dietary soy - and not to the high levels of isoflavones found in soy pills. He also comments that the studies cannot completely rule out the potential for risk. However, he concludes that "the bulk of the experimental evidence points to a protective effect of soy consumption on endometrial cancer risk."
