After being discharged from hospital, many tumor patients are always worried about their condition and always want to have a checkup in hospital, but they don’t know what to check in the end. According to clinical experience, the general recommendations are as follows: three routine tests: blood routine, urine routine, biochemical routine, which can indicate the condition of white blood cells, red blood cells and platelets, and also look at liver and kidney function. Tumor markers: It is best to check a full set of tumor markers. Overall observation. Ultrasound of abdomen: It helps to detect abdominal organs and retroperitoneal metastatic lesions early. Brain CT: Brain is the common site of tumor metastasis. Whole body bone imaging: It can detect bone metastases at an early stage. As long as tumor patients should have this examination regularly, especially for lung cancer, breast cancer and prostate cancer patients. Lung CT: Patients with lung tumor surgery should undergo lung CT examination because the normal structure has been changed due to the surgery. The above is only a personal suggestion, please refer to it as appropriate.
