Breast cancer spreading generally refers to the discovery of metastasis. If the breast cancer only metastasizes to the lymph nodes in the ipsilateral armpit, there is still a possibility of cure, but if distant metastasis occurs, it usually cannot be completely cured. 1. If the breast cancer only spreads to the ipsilateral axillary lymph nodes, preoperative chemotherapy can be carried out first. After the axillary lymph nodes are shrunken and controlled, radical surgical resection will be performed, followed by postoperative adjuvant therapy. Through comprehensive treatment, some patients can still get 5 years, 10 years or even longer survival, and thus get clinical cure. 2. Once breast cancer has metastasized to liver, lungs, brain tissue and bones, the chance of radical surgical resection is usually lost, and generally it cannot be completely cured. It can only inhibit the spread of cancer cells through radiotherapy or targeted therapy, which can only play a role in controlling, improving the quality of life and prolonging life. It is recommended that patients actively follow the doctor’s instructions to cooperate with the treatment, don’t give up easily, and pay attention to psychological adjustment, which can help the recovery of the condition.
