There’s some good news about the role that dairy plays in the prevention of breast cancer. This comes from the American Cancer Society.

A new American Cancer Society study finds low fat dairy products may reduce the risk of postmenopausal breast cancer, supporting the hypothesis that dietary calcium and/or some other components in dairy products may reduce the risk of the disease. The study found women who consumed two or more servings of dairy products per day had up to 20 percent lower risk of postmenopausal breast cancer compared to women with the lowest consumption of dairy products. The association was slightly stronger among women with estrogen-receptor positive tumors, the most common type.

The study is published in this month’s issue of Cancer Epidemiology, Biomarkers, and Prevention.
