Early breast cancer may need radiotherapy after chemotherapy. If the patient’s condition is mild, the breast lump is small and no lymph node metastasis has occurred, the patient does not need radiotherapy after chemotherapy; if the patient’s condition is serious, the breast lump is large and lymph node metastasis has occurred, the patient needs radiotherapy after chemotherapy, which can inhibit the metastasis of the cancer cells to a certain extent and prolong the patient’s life. The drugs used in chemotherapy for breast cancer patients mainly include epirubicin, docetaxel or piroxicam, etc. The drugs are pushed into the body through intravenous drip, so that the blood can circulate all over the body, which can play a very good therapeutic effect. Patients are advised to go to the hospital for regular check-ups and seek immediate medical attention if there is any abnormality.
