Gynecomastia refers to the development of male breasts during adolescence due to a hormonal imbalance. Today, treating this with male breast reduction surgery is quite common. The procedure's popularity also means that it is very safe and precise. Now, you may be wondering why surgery is even necessary. Well, surgery is the only treatment option for male breasts. Unlike chest fat, which you can burn with exercise, male breasts involve breast tissue and gland development.
