Patients with early stage breast cancer usually do not need chemotherapy after surgery, but patients with risk factors for recurrence may also need 4 cycles of chemotherapy. Patients with early stage breast cancer have small tumors and no metastases, including lymph node metastases or distant metastases, etc. After the disease is detected and the diagnosis is clear, surgery is usually sufficient. Depending on the patient’s condition, axillary lymph node dissection can also be done if necessary, which is a modified radical surgery for breast cancer. After surgery, if the patient is hormone receptor positive, endocrine medication will be required. After surgery, patients are recommended to come to the hospital for regular check-ups, usually once every three months and once every six months after two years. In addition, it is recommended that patients should eat as lightly as possible in their daily lives.
