New Resource--Breast cancer risk in relation to occupations with exposure to carcinogens and endocrine disruptors: a Canadian case–control study, NNEWH

A new Canadian study conducted by co-principal investigators James Brophy and Margaret Keith and an international, multidisciplinary team of co-investigators demonstrates that women working in particular occupations have an increased risk of developing breast cancer. The National Network on Environments and Women's Health (NNEWH) partnered with Brophy and Keith in the study's exposure assessment of automotive plastics workers in the Windsor, Ontario region. The research results are a valuable addition to growing evidence linking breast cancer and other diseases with exposure to toxic chemicals, and in particular, toxins in the workplace.

Women who are exposed to carcinogens and endocrine disrupting chemicals at work may be at a greater risk for developing cancer. Many plastics have been found to release estrogenic and carcinogenic chemicals. Significantly, women working with plastics in the automotive industry for ten years were found to be more than twice as likely to develop breast cancer, with women in that sector who are pre-menopausal being five times more likely.
