Tip: Soy can help prevent breast cancer return

Eating foods rich in soy may help protect against the recurrence of breast cancer, according to a new study.

Researchers at Vanderbilt-Ingram Cancer Center analyzed the data of 5,042 breast cancer survivors in China and found that women who consumed the highest amount of soy foods were at lower risk for a recurrence of the disease after four years than those who ate fewer soy foods. The women who ate the most soy foods also had a reduced risk of death. Researchers advised against taking soy supplements because the capsules often lack other nutrients found in soy foods and therefore may not deliver the same benefits.

The research counters previous studies that indicated the estrogen-like compounds in soy might promote tumor regrowth in breast-cancer survivors.

The study was published in the Dec. 9 issue of the Journal of the American Medical Association.
