ScienceDaily (Oct. 18, 2012) — Breast-feeding reduced the risk for estrogen receptor-negative and progesterone receptor-negative breast cancer, according to results presented at the 11th Annual AACR International Conference on Frontiers in Cancer Prevention Research, held in Anaheim, Calif., Oct. 16-19, 2012.

"We found an increased risk for estrogen receptor- and progesterone receptor- (ER/PR) negative breast cancer in women who do not breast-feed, but in women who have children and breast-feed, there is no increased risk," said Meghan Work, M.P.H., doctoral student in the department of epidemiology at Columbia University's Mailman School of Public Health in New York, N.Y.
