Many of us have marveled at the sight of a pack of pups suckling at their mother's teats. And we might have seen pictures and statues of fertility goddesses with rows of breasts across their chests. Perhaps we have thought that multiple breasts in humans were just the stuff of fantasies. But some people do have one or more extra breasts, medically called POLYMASTIA. Also known as SUPERNUMERARY BREASTS, they can come with or without nipples and areolae. Most often these mammary marvels are not noticed until puberty, when they start to develop in response to sex hormones.
Extra breasts do not just arise on the chest; they can develop on the buttocks, neck, shoulders, and back as well. And both men and women can have them. While multiple breasts can certainly be a cosmetic concern, any problem that can develop in a normal breast, including cancer, can occur in an extra one as well. And defects in the kidneys and other organs are sometimes seen in people with extra breasts.
