This document summarizes evidence on potential links between endocrine disrupting chemicals (EDCs) and breast cancer risk. It discusses studies finding associations between breast cancer and exposures like diethylstilbestrol (DES), post-menopausal hormone use, organochlorines like DDT and dieldrin, polychlorinated biphenyls, and chemicals in the home and workplace like phthalates and bisphenol A. While evidence is mixed, some chemicals appear to modestly increase risk, and windows of exposure during development may be important to consider.
