If breast cancer metastasizes to the axillary lymph nodes, excluding metastasis from other parts of the body, some patients can be clinically cured if they are given comprehensive treatments such as radical surgery, endocrine therapy and chemotherapy in time. Axillary lymph node is a common metastatic site of breast cancer. If it is not accompanied by metastasis from other parts of the body, radical breast cancer surgery combined with axillary lymph node dissection can be performed, and radiotherapy or endocrine therapy can be given after the surgery, and some patients need to be given preoperative neoadjuvant chemotherapy before surgery, and the general five-year survival rate is around 70%-80%. If accompanied by metastasis of distant tissues and organs, the disease is mostly in advanced stage, radiotherapy, targeted therapy, immunotherapy and other comprehensive treatment methods can be taken to slow down the progress of the disease, but it is difficult to achieve a clinical cure. It is recommended that patients actively cooperate with doctors to avoid delays.
