Male mastectomy includes male breast hyperplasia and male breast cancer, etc. How to do it depends on the scope and size of the mastectomy as well as the specific disease. 1. Mastopexy: In the case of male breast enlargement, the entire mammary gland is removed. Local anesthesia, epidural or general anesthesia is available. After the patient lies down, the skin of the nipple-breast area is sterilized by rubbing it with iodophor antiseptic solution. An incision is made on the surface of the breast and the entire gland is removed intact. 2. Breast Cancer: In the case of male breast cancer, a modified radical mastectomy is needed. The scope of excision must be large enough, and the lymph nodes in the armpit should also be cleared as much as possible. When men need to undergo mastectomy, they should go to regular hospitals in time and have targeted surgery by professional doctors.
