The incidence of breast nodules and breast masses is increasing. In the past, the treatment of breast masses was usually based on surgical incision, and the traditional open surgical incision is obvious, traumatic and leaves large scars after surgery. The Department of Mammary Gland Surgery has developed minimally invasive rotational mastectomy to treat benign breast nodules and tumors. Based on minimally invasive theory, minimally invasive mastectomy is the development and innovation of today’s breast treatment technology. It is a minimally invasive surgery guided by ultrasound image, using the principle of combining vacuum suction and rotary incision, and only a 3mm incision is needed to fully remove the mass. Its advantages are: 1. Small surgical trauma, only local anesthesia is required, and the operation time is short. 2.Less bleeding during the operation, only a very small incision. 3. Almost no scars and satisfactory appearance after surgery.
