BPA Exposure Early in Life Raises The Risk of Prostate Cancer

Early exposure to the chemical BPA is linked to the development of prostate cancer later in life, according to results from a new clinical study conducted at the University of Illinois in Chicago. BPA is a chemical commonly found in plastic food storage containers, water bottles, and the lining of canned goods, and is thought to act as an estrogen—a hormone that can sometimes promote cancer. To study its effects, researchers implanted mice with developing human prostate cancer cells and fed them BPA in doses similar to what people encounter in their daily lives. The results of the study concluded that mice exposed to BPA had a 33 percent risk of developing prostate cancer, while those not exposed had a 12 percent risk. The chemical is thought to ‘reprogram’ developing prostate cancer cells, making them more susceptible to the cancer causing effects of estrogens later in life.
