Red Meat Intake and Risk of Breast Cancer Among Premenopausal Women.

The article discusses the results of a study on the association of red meat consumption and risk of breast cancer among premenopausal women aged 26-46 participating in the Nurses' Health Study II. A 12-year follow-up of the 90,659 participants documented 1,021 cases of invasive breast carcinoma. Greater red meat intake was strongly related to higher risk of breast cancers that were estrogen and progesterone receptor positive, but not with progesterone and estrogen negative.
