Minimally invasive excision of breast masses is a relatively new surgical procedure, and given its advantages, it has given such procedures great room for development in China, and it can be said that minimally invasive surgery of the breast is done more than abroad. The minimally invasive surgery that is more widely done in China is guided by ultrasound, and the whole procedure is clearly displayed on the screen of ultrasound, while the wound is only 0.5-1cm. Compared with traditional surgery, it is an innovation and a great opportunity for young patients, for scar patients, for patients with high cosmetic requirements, for patients with multiple tumors, and for patients who cannot reach the swelling with their hands, it is a great It is a great boon to the patients. The minimally invasive knife is advanced to the underside of the tumor under ultrasound guidance through a minimal wound, and the tumor is divided into several parts, excised and removed one by one, from the bottom up. The whole process is clearly displayed on the monitor, whether the tumor is cut cleanly or not, and whether there is any residue, it is clear! After the surgery, the wound is small and the appearance of both breasts is basically unchanged, which is very ideal. Some patients even have multiple tumors removed through one or two incisions, avoiding the tragedy of having both breasts covered with scars, which is more perfect.
