For men who have gynecomastia, or enlarged breasts, there can be a lot of negative emotions. They may feel shame, insecurity or humiliation because of the large size of their male breasts. Nearly half of all men have some excess fat that is localized in breast tissue on one or both breasts. Over 65 percent of all disorders related to male breasts are due to gynecomastia. Surgery and liposuction are the procedures that are typically used for treatment of male breast disorders.
