Whether or not to do chemotherapy for early stage breast cancer depends on the patient’s condition. Breast cancer is one of the most common malignant tumors in women, and it is also one of the most effective tumors in solid tumors with the application of chemotherapy. The treatment of breast cancer is a comprehensive treatment mainly based on surgery and supplemented by radiotherapy. Surgery is preferred for early stage breast cancer, and postoperative chemotherapy is generally recommended when there are axillary lymph node metastases; whether adjuvant chemotherapy is used for those without axillary lymph node metastases is still controversial, and it is generally believed that those with high-risk factors for recurrence, such as the diameter of the primary tumor >2cm and poor grading of histological examination, need to be suitable for the application of postoperative adjuvant chemotherapy. The development of treatment strategies for breast cancer patients is recommended under the guidance of specialized doctors.
