The use of lumpectomy is a typical representative of minimally invasive surgical techniques, and breast surgery uses this technique to achieve minimally invasive surgery while ensuring safe and reliable surgery and tumor removal, and to obtain the triple effect of functional preservation and aesthetic appearance. Breast lumpectomy has been gradually carried out in many medical centers around the world, including Beijing, Shanghai, Guangzhou, Jiangsu, Shandong, Wuhan, Liaoning, Chongqing, Hebei and Jiangxi, and has been welcomed by both doctors and patients, showing a rapid development momentum, and has become a new surgical treatment modality with great clinical potential and good prospects, which is welcomed by both doctors and patients. The procedure is completed by lipolysis, liposuction, establishment of surgical access and surgical operation. The difference with laparoscopic surgery lies in the formation of an artificial surgical cavity in the breast surgery area after lipolysis and liposuction before the surgery starts, and then the breast surgery operation is completed in this limited cavity. The main advantages are: less trauma, no visible surgical incisions on the breast surface, low incidence of postoperative complications (upper limb edema 7% vs. 56%), maximum avoidance of damage to the vascular nerves and lymphatic vessels, good skin conditions for breast reconstruction (preservation of the nipple areola and all skin of the breast), restoration of breast appearance by implantation of appropriate volume of prosthesis; at least no less than traditional breast-conserving surgery in terms of efficacy and cosmetic effect. In terms of efficacy and cosmetic results, it is at least no less than traditional breast-conserving surgery, and even better than open modified radical surgery, which can improve the quality of life of patients. Currently, the most mature lumpectomies performed in breast surgery include lumpectomy for axillary lymph node dissection, lumpectomy for subcutaneous breast adenomectomy, lumpectomy for small incision modified radical breast cancer, and lumpectomy for breast implant removal. Nowadays, lumpectomy technology has been widely used in surgery, and the combination of cosmetic surgery, plastic surgery and surgery has penetrated into all aspects of breast surgery, which has obviously changed the concept of surgical treatment of breast tumor and brought breast surgery into a new stage – the humanized stage of minimally invasive surgery and function preservation. It is reasonable to believe that the overall treatment strategy of breast cancer will continue to develop in the direction of combining more minimally invasive and targeted surgical treatment with more selective systemic treatment, and that the chance of survival and quality of life of women with breast cancer will become closer to that of normal women, so that they can return to society “perfectly”.
