Breast cancer with 6 lymph nodes found in the armpit generally belongs to stage III, which is more serious and can be treated by surgery, chemotherapy and radiotherapy. 1. Surgery: breast cancer with 6 lymph nodes found in the armpit needs to be treated by surgical excision, such as radical mastectomy, axillary lymph node dissection, modified radical mastectomy and so on. However, after surgery, patients may have lymphedema, numbness of upper limbs and activity disorder. 2. Chemotherapy: chemotherapy is necessary for patients with breast cancer with 6 lymph nodes found in the axilla. The residual tumor cells from the diseased part of the tumor removed by surgery need to be treated by chemotherapy. Commonly used chemotherapeutic drugs such as cyclophosphamide and paclitaxel drugs should be used under the guidance of doctors. 3. Radiotherapy: patients with breast cancer with 6 lymph nodes found in the armpit need to be treated with radiation for the local tumor after surgery. Patients with breast cancer with 6 lymph nodes found in the armpit should go to the hospital in time and choose the appropriate treatment method under the doctor’s advice.
