The above-mentioned method of breast cancer treatment can also preserve the pectoral muscle, the intercostal brachial nerve and the thoracic dorsal nerve without affecting the function of the pectoral muscle and the sensory function of the affected upper limb, so that the movement, sensation and exertion of the upper limb are not affected after surgery, and normal activities and labor can be resumed as before surgery, such as laundry, playing ball and dancing. In addition, the advanced ultrasonic knife cutting technology minimizes the impact on the lymphatic reflux of the upper limb, and no upper limb edema occurs after surgery. In addition, the incision is beautiful and flat, does not affect the cosmetic effect after dressing, and is conducive to future breast reconstruction. In recent years, breast cancer surgery with skin preservation and nipple and areola preservation has also been carried out, which is more conducive to breast reconstruction and meets patients’ needs for beauty while pursuing health. In the postoperative care and rehabilitation, the drains are removed early, the rehabilitation starts early, and the upper limb function is restored early. This treatment enables breast cancer patients to avoid subcutaneous fluid accumulation and flap necrosis after surgery, and to perform simple actions such as combing hair and washing face on the second day after surgery, and to do significant upper limb functional rehabilitation gymnastics on the sixth day after surgery. International guidelines stipulate that at least 10 lymph nodes should be obtained for breast cancer surgery. The maximum number of lymph nodes that can be obtained in the nail and breast surgery at this hospital is more than 60, and the average number of lymph nodes obtained is 30. What is the significance of obtaining more lymph nodes? Axillary lymph nodes are one of the indicators of the severity of the disease, and the more lymph nodes obtained, the more accurate the judgment of the severity of the disease. How can we obtain so many lymph nodes? In addition to superb technique, the pathology department of the hospital is the first in China to adopt lymph node lysis technique to obtain the full number of lymph nodes in the specimen, and to make 6 slices for each lymph node to minimize the false negative rate, with the aim of ensuring that patients can get the most accurate diagnosis. The above-mentioned optimal treatment plan for breast cancer patients according to international guidelines ensures efficacy, alleviates side effects, less damage to patients, better postoperative aesthetic results, etc. It is known that the 10-year survival rate of more than 300 clinical treatment cases in the department is over 90%.
