The November 2012 study by Brophy and Keith on Breast cancer risk in relation to occupations with exposure to carcinogens and endocrine disruptors: a Canadian case control study. This study showed that women who work in certain occupations, most notably automotive plastics manufacturing and food packaging, have a higher risk of breast cancer as young women.
An accompanying study by DeMatteo et al on Chemical Exposures of Women Workers in the Plastics Industry with Particular Reference to Breast Cancer and Reproductive Hazards showed higher than normal workplace exposures to endocrine disrupting chemicals among women who work in the plastics industry and have a higher than normal risk of breast cancer.
The February 2013 Congressional Mandated Committee report Breast Cancer and the Environment: Prioritizing Prevention Report of the Interagency Breast Cancer and the Environment Research Coordinating Committee (IBCERCC).

The State of the Science of Endocrine Disrupting Chemicals-2013 that finds that the rates of endocrine related cancers (breast, ovarian, prostrate, testicular and thyroid) and other hormone-related diseases are increasing globally and that reducing chemical exposures needs to become an important focus.
In Canada, the National Network on Environments and Women's Health has created a great new set of resources including summaries of the first two studies described above, a Plastics & Breast Cancer Q & A and a Women & The Automotive Plastics Industry quick facts guide to protecting your health.
