Breast cancer is one of the most common malignant tumors in women, but if detected and treated early, the cure rate can reach about 70%, and the survival rate is high and the recurrence rate is low. Even in case of recurrence and metastasis, active treatment can significantly prolong the survival and improve the quality of life of patients. Therefore, standardized treatment, regular review and healthy life are crucial to the cure rate and survival rate of breast cancer patients. After the treatment is finished, insist on regular review. Depending on the type and stage of the disease, patients can choose from surgery, chemotherapy, radiotherapy, targeted therapy and endocrine therapy. Generally speaking, surgery, chemotherapy, radiotherapy and targeted therapy can be completed within six months to one year. If endocrine therapy is required, it takes a little longer, usually 5-10 years of regular medication. During and after the end of regular treatment, patients still need to visit the hospital for regular follow-up reviews. In general, the interval between reviews is 3 months within 1 year after surgery; 3-6 months within 2 years after surgery; every 6 months after 2 years after surgery; and 5 years after surgery, every year can be considered. The purpose of regular review at the hospital is twofold: for those who need follow-up medication, the medication can be prescribed regularly and taken on time; for those who have a recurrence, the review can detect it at the first time and get active treatment. If you do not insist on regular review, when the symptoms appear, the disease is often more serious. The items that need to be reviewed regularly include blood tests, ultrasound, chest X-ray and other examinations. Blood tests include routine blood tests, biochemical tests, tumor markers, etc. Ultrasound tests include breast ultrasound, local lymph node ultrasound and abdominal ultrasound. If the patient has discomfort symptoms in a certain part of the body during the process, CT, MRI, bone scan, etc. will be done under the guidance of the doctor to further clarify whether there is recurrence and metastasis.
