Gynecomastia or excess development of breast tissue, occurs in as many as 40-60% of men. This condition can cause extreme embarrassment, social inhibition, and self-consciousness for boys and men who suffer from it. Male breast reduction surgery is performed under general anesthetic and although it is generally performed as a day case, you may need to stay in the hospital for one or two nights. The cosmetic surgeon will cut around the dark skin surrounding the nipple (the areola) or under your arm, and the excess fat, skin, and breast tissue will be removed. Liposuction can also be performed at the same time to remove excess fat in the area.
