Soy reduces breast cancer risk by receptor status
NEW YORK (Reuters Health) - Rather than protecting against all breast cancers, high levels of soy food consumption appears to specifically reduce the risk of estrogen receptor (ER)-positive tumors and human epidermal growth factor receptor 2 (HER2)-negative tumors, Japanese researchers report in the International Journal of Cancer.
Dr. Takeshi Suzuki, at Aichi Cancer Center Research Institute in Nagoya, and associates conducted a study of 678 women with breast cancer and 3,390 controls matched by age and menopausal status with no history of cancer.
