If breast cancer is diagnosed at an early stage, patients should choose surgery in a timely manner. The classic surgical procedure is modified radical resection, which costs less than $10,000 if treated in a tertiary care hospital and is reimbursed by medical insurance. For breast cancer patients, after surgery, adjuvant treatment plan should be chosen according to the detailed pathological stage and biological behavior of the tumor, and for patients with combined lymph node metastasis, systemic intravenous chemotherapy is also required. For breast cancer patients with intraductal cancer or lobular carcinoma in situ, no additional chemotherapy is needed after surgery, but regular follow-up and observation are required, and the cost is not too high. The cost of performing intravenous chemotherapy is about RMB 3,000 per cycle. For breast cancer patients, 6-8 cycles of chemotherapy are required after surgery, and close follow-up and observation are needed regularly after breast cancer surgery.
