Gynecomastia surgery is a procedure to remove excess fat, glandular tissue and/or skin from overdeveloped or enlarged male breasts. In severe cases of gynecomastia, the weight of excess breast tissue may cause the breasts to sag and stretch the areola (the dark skin surrounding the nipple). In these cases, the position and size of the areola can be surgically improved and excess skin may need to be reduced, leading to additional scarring. Gynecomastia may result from hormonal changes, heredity, disease, or the use of certain drugs, and can present unilaterally (one breast) or bilaterally (both breasts).
