Review is needed three months after breast cancer surgery, including blood tests such as blood routine, liver and kidney function, tumor markers, as well as ultrasound, chest X-ray, isotope whole body bone scan and other tests. 1. Blood examination: After breast cancer surgery, it is routine to carry out blood system examination, such as blood routine, to know whether the patient has decreased white blood cells and anemia, meanwhile, check the liver and kidney function, to make it clear whether there is damage to the liver and kidney function, and give timely and appropriate treatment if necessary, and detect the changes of tumor markers to prevent recurrence. 2. Color ultrasound: For example, breast color ultrasound can judge the recovery after breast surgery and review whether there is recurrence or lymph node metastasis. In addition, abdominal ultrasound can be performed to examine the liver, gallbladder, pancreas, spleen, kidneys and other organs, to understand the morphology and function of each organ and to determine whether the patient has metastases in the abdominal organs. 3. Chest X-ray: Chest X-ray can understand the condition of the lungs, indirectly determine whether the patient has metastasis in the chest, and at the same time, understand whether the patient has developed lung lesions, such as pneumonia, after the operation. 4. Isotope whole-body bone scan: to determine whether there are bone metastases.
