Breast cancer chemotherapy followed by surgery may be a more serious case, which is usually used to treat some intermediate and advanced breast cancers. When some middle and advanced breast cancer lumps are large in size and cannot be completely removed by direct surgery, chemotherapy should be given first and then surgery should be considered when the tumor size decreases. In some breast cancer patients, the size of the cancerous lumps is relatively large, and the surrounding lymph nodes are also enlarged. At this time, direct surgery may not be able to remove the lumps completely, so chemotherapy is needed to wait for the lumps to decrease before considering surgery, which can reduce the chance of recurrence after surgery. At present, chemotherapy followed by surgery for breast cancer is more effective, which can effectively inhibit the growth and spread of cancer cells, and can make middle and late stage breast cancer patients have a better prognosis. Breast cancer can be treated with chemotherapy followed by surgery, and regular treatment must be carried out under the guidance of doctors, as well as maintaining a comfortable mood, regular functional exercise in the later stage, and regular checkups, which can usually lead to a gradual recovery of health.
