Parabens are chemicals that can mimic the hormone estrogen in the body. As estrogen has been shown to increase breast cancer risk, some people have asked if parabens found in some cosmetics and shampoos will also increase breast cancer risk. Many studies have shown that parabens in the quantities found in personal care products are safe. A recent study of human breast cancer cells suggests that in certain conditions, parabens could help some breast cancer cells grow. It is important to remember that this is early research; this single laboratory-based study does not conclusively prove that parabens are dangerous. More work, including human studies, needs to be done to understand if parabens increase cancer risk. (01/16/2016)
