Gynecomastia surgery, which is mainly performed for enlarged breast development and breast diseases, is generally categorized into minimally invasive surgery and open surgery. 1. Minimally invasive surgery: Due to excessive secretion of male hormones, which leads to gynecomastia hypertrophy, minimally invasive surgery is often used, mainly through minimally invasive rotary needles and endoscopes, to excise excess breast tissues, fat and improve the shape, so that the gynecomastia chest becomes flat. 2. Open Surgery: Due to various causes of breast enlargement and hypertrophy in men, which affects their life, open surgery can be used to remove excess breast tissue, radiate the incision as the center, and remove the enlarged glands to improve the abnormal breast development. Gynecomastia surgery, mainly for breast-related diseases, is recommended under the formal guidance of a doctor.
