The modalities of gynecomastia surgery can be categorized into minimally invasive surgery and open surgery. 1. Minimally invasive surgery: During minimally invasive surgery, an incision of about two millimeters needs to be made in the male breast area, and the breast tissue will be rotary cut and removed to achieve the treatment effect. In addition, the breast gland can also be removed through minimally invasive lumpectomy, which leaves a smaller incision in the breast area. 2. Open Surgery: Open surgery involves making an incision underneath the male areola, entering the breast through the incision, stripping the gland and removing the peripheral nerves if necessary, and then suturing the incision site. Men with breast development who require surgery are advised to visit a specialist breast surgeon and undergo the appropriate surgical treatment strictly in accordance with the doctor’s instructions.
