BPA and Breast Cancer?

Bisphenol A, or BPA, is widely used in manufacturing plastic containers, the lining of cans, and some cash register receipts. This chemical acts as a endocrine disruptor, mimicking estrogen in the body. New research in mice suggests that BPA exposure while the fetus is developing may cause cellular changes that predispose the infant mouse to an increased risk for breast cancer later in life. BPA appears to be acting like DES, known as diethylstilbestrol. New research confirms that women who were exposed to DES in utero have nearly twice the usual risk of breast cancer in middle age.
