Most tumors in the kidney are treated with surgery, and if surgery is lost, radiotherapy or chemotherapy is required. Tumors in the kidney are also divided into benign and malignant. The gold standard for diagnosing benign and malignant tumors is tumor aspiration biopsy, which is diagnosed by pathology. If the tumor is benign, relatively large and has compression symptoms, such as hypertension, hydronephrosis and severe back pain, it needs to be treated, usually with surgery. If the benign tumor is small, it can be left untreated for the time being, and the CT of both kidneys can be reviewed dynamically once every three to six months; if it is a malignant tumor, it is usually treated by surgery, which is the only way to remove it completely and prevent metastasis. In addition, if the tumor has metastasized and the chance of surgical treatment is lost, only radiotherapy or chemotherapy can be given. But even with radiotherapy and chemotherapy, the survival time will not be too long.
