Gynecomastia – Male Breast Reduction – is a medical term that comes from the Greek words for “women-like breasts.” Though this oddly named condition is rarely talked about, it’s actually quite common. Gynecomastia affects an estimated 40 to 60 percent of men. It may affect only one breast or both. For men who feel self-conscious about their appearance, breast-reduction surgery can help. The procedure removes fat and or glandular tissue from the breasts, and in extreme cases removes excess skin, resulting in a chest that is flatter, firmer, and better contoured.
