Cancer survivors had been warned away from soy products because they contain chemicals called isoflavones that some worried might "increase" the risk of cancer recurrence among breast cancer patients.
Researchers followed 16,000 such women in a study just presented to the American Association of Cancer Research. They concluded that it may be beneficial for women to include soy food as part of a healthy diet, even if they have had breast cancer. The findings do not apply to soy supplements.
