The overall five-year survival of patients with stage III breast cancer is about 50%-60%, but this is only a statistical concept, there are many patients who can live longer than that, there are no clear statistics on how long they can live, and it is possible that they can reach the state of complete cure. After breast cancer surgery, the next treatment plan should be decided according to the pathological results. First of all, the surgery itself should be standardized, so that the mammary gland can be completely removed and the axillary lymph nodes can be cleared without cancer residue. Secondly, the adjuvant treatment plan should be decided according to the pathological results, such as chemotherapy or endocrine therapy, oral tamoxifen, or oral anastrozole, exemestane, letrozole for postmenopausal women, etc. If patients are HER2-positive, targeted drugs can be used for treatment. It is important to come to the hospital for regular follow-ups, and if there is metastasis or recurrence, timely treatment should be given.
