Breast cancer is salvageable, and the overall treatment outcome is relatively good for most breast cancer patients. Unless the patient has very advanced tumor, large tumor, ruptured and multiple metastases, including axillary lymph node metastasis, supraclavicular lymph node metastasis, rib metastasis, lung metastasis, etc. the treatment outcome is poor. Most breast cancer patients can be treated with surgery, including modified radical breast cancer surgery or radical breast cancer surgery, which can be used such as breast-conserving surgery to remove the tumor while clearing the axillary lymph nodes. After surgery, the next adjuvant treatment plan is decided according to the pathological staging results and immunohistochemistry results, and chemotherapy or immunotherapy, endocrine therapy, etc. are used, and the overall effect is better.
