Soy foods are rich in isoflavones, a major group of phytoestrogens that have been hypothesized to reduce the risk of breast cancer. To evaluate the association of soy food intake after diagnosis of breast cancer, with total mortality and cancer recurrence, 5033 surgically treated breast cancer patients were tracked for more than 3 years.
Soy food intake, as measured by either soy protein or soy isoflavone intake, was found to be inversely associated with mortality and recurrence. The researchers concluded that soy food consumption is significantly associated with decreased risk of death and recurrence of breast cancer. (more…)
