The breast is an important female organ and an important part of a woman’s physical beauty. The absence of the breast and the change of its shape often cause unsightly appearance and further psychological damage to the woman. Modern treatment concepts focus on treating the disease while paying more attention to the appearance of the breast and minimizing the physical and psychological trauma to the patient. Minimally invasive treatment of the breast is developing rapidly, and breast lumpectomy has been gradually carried out in tertiary hospitals in major cities in recent years. Recently, a number of breast lumpectomy cases have been successfully performed in the Department of General Surgery. The patient was placed in supine position, and after the operation space was established by liposuction and inflation method, Yu operated the same lumpectomy. Deputy Director Yao Chengcai of our department has rich experience in breast surgery and lumpectomy, and recently performed breast lumpectomy for many patients with smooth procedures and no postoperative complications. Patient 1, a 44-year-old female, was admitted to the hospital with bilateral breast masses. After biopsy of the masses, the pathology indicated atypical ductal hyperplasia. Deputy Director Yao Chengcai combined the patient’s medical history, pathological results and personal wishes, and finally suggested the patient to undergo lumpectomy with simple subcutaneous mastectomy with preservation of the nipple areola, aiming to treat the patient’s disease on the basis of ensuring the patient’s appearance as much as possible. The procedure went smoothly with minimal intraoperative bleeding, and the patient recovered well after surgery without complications such as subcutaneous emphysema, skin flap necrosis, nipple areola necrosis, or bleeding. Patient 2, female, 48 years old, was admitted to the hospital for finding a left breast mass, which was located at the 3 o’clock position nipple 2 cm, size about 2.0 cm, pathology after biopsy suggested invasive ductal carcinoma, the patient had breast-conserving indications, and after consultation with the patient, the patient did not accept breast-conserving surgery, and finally decided to have a sex-lumpectomy subcutaneous simple mastectomy. The procedure went smoothly and the patient recovered well after surgery. The drainage tube was removed 5 days after surgery and no postoperative complications occurred. Patient 3, a 52-year-old female, came to our hospital with a diagnosis of breast cancer from a foreign hospital. The patient’s primary focus was less than 2.0 cm and located in the outer upper quadrant. The procedure went smoothly and the postoperative recovery was good with no associated complications. The previous surgical procedure for breast cancer was basically a modified radical mastectomy, and the absence of the breast, especially the nipple and areola, often caused great psychological stress to the patient after surgery. The maturation of comprehensive breast cancer treatment has led to a gradual shift towards minimally invasive surgery. The amount of bleeding, recovery time and complication rate of breast lumpectomy are significantly lower than those of traditional surgery. This is undoubtedly a blessing for breast cancer patients and represents a major leap forward in the level of surgical treatment for breast cancer in the Department of General Surgery.
