by: cancercompass

Japanese researchers have found foods high in soy protein reduce the risk of estrogen receptor cancers, according to results published recently in the International Journal of Cancer.

Researchers at the Aichi Cancer Center Research Institute in Nagoya say soy consumption reduced the risk of estrogen receptor (ER)-positive and human epidermal growth factor receptor 2 (HER2)-negative tumors.

During the case-control study, researchers observed 678 cancer cases and 3,390 controls matched by age and menopausal status with no history of cancer. According to the study a "significantly reduced risk" of breast cancer was found among women with the highest soy intake who were ER-positive, HER2-negative or both.

Overall, the study's findings concluded soybean products have potential benefit in preventing some breast cancers.
