Patients with breast cancer are deeply distressed by the inconvenience, social confusion and psychological impact of the surgery. For example, swelling of the upper extremities, limitation of limb movement and social activities, etc. Since many years ago, all breast cancer patients underwent radical surgery and extended radical surgery based on the theories and practices at that time, and after 1984, breast revision radical surgery was gradually performed, and after 1995, breast cancer surgery with breast preservation was gradually started. With new advances in clinical medicine, new theories and practices, some patients today can still achieve long-term survival without surgery. Nowadays, many large hospitals across the country have breast departments, breast centers, and breast hospitals. The examinations include ultrasound, mammography, infrared examinations, and MRI (magnetic resonance imaging) examinations, although all of these examinations, ultrasound examinations, which are overcrowded in large hospitals and require a wait of more than a week, and MRI examinations, which are expensive, have relative shortcomings. An examination by an experienced surgeon is actually the most important. If the patient has the financial power, ultrasound, breast MRI, mammogram and ultrasound-guided biopsy can be done, and pathology results will be available in a week. If cancer is confirmed, the patient will be treated. If there is no financial condition, after examination by experienced surgeon, you can go directly to biopsy and enter the treatment procedure after clear diagnosis. With definite pathological results, you can proceed to chemotherapy before surgery, or you can proceed directly to surgery. After surgery, depending on the pathology results, chemotherapy is then administered. The survival of chemotherapy before surgery and chemotherapy after surgery is the same in foreign countries as concluded by long-term follow-up. Pre-operative chemotherapy has many advantages, for example, it can see whether the chemotherapy regimen used for the patient is effective, whether the tumor shrinks, whether it is sensitive to chemotherapy drugs, it can reduce the aggressiveness of tumor cells, and create conditions for preserving breast surgery, but pre-operative chemotherapy can also bring some problems, such as heart and cerebrovascular complications during chemotherapy and loss of surgery, pre-operative chemotherapy can make the tumor and metastatic lymph nodes shrink or even disappear. Preoperative chemotherapy can shrink or even disappear the tumor and metastatic lymph nodes, which brings uncertainty to the clinicopathological staging after surgery, thus bringing some confusion to the chemotherapy regimen chosen after surgery and whether to carry out radiation therapy. Pre-operative chemotherapy may cost more in terms of energy, material and financial resources for the patient and family than post-operative chemotherapy. Breast cancer surgery with breast preservation is a clinical hot spot nowadays, but there are many requirements before breast preservation surgery can be performed, not all patients can undergo such surgery, and there are also requirements for medical institutions to perform such surgery. Endocrine therapy is also a hot spot. Some patients without surgical conditions can undergo such treatment, with the progress of pharmacology and clinical drug applications, anacrazole, letrozole, exemestane, toremifene and so on. For breast cancer treatment, the results are similar. After surgery, radiotherapy and chemotherapy, the immune system of breast cancer patients is severely attacked, therefore, after the above treatments, it is necessary and feasible to combine with immunotherapy and Chinese herbal medicine to regulate the treatment. Breast cancer is a systemic disease and individual differences exist, although the same treatment, the same pathology, the same clinical stage, the same chemotherapy regimen but the survival is completely different. This situation often occurs in clinical practice.
