With the approval of the State Food and Drug Administration, targeted drugs for the treatment of advanced renal cancer have been officially launched in China. The early symptoms of kidney cancer are not obvious. When there is no painful hematuria, waist mass, and triad of back pain, the disease has progressed to the middle and late stages. Scientists have found effective ways to achieve triple anti-tumor: one is to inhibit the growth of tumor cells, the other is to destroy the nutritional metabolism of tumor cells, and the third is to prevent tumor angiogenesis. This is currently the first option after the failure of targeted therapy for advanced renal cancer, which can effectively prolong the survival time of patients. It is reported that the occurrence of kidney cancer is related to heredity, excessive obesity, smoking, and long-term exposure to chemical carcinogens, such as engaging in the processing of petroleum products and chemical products. It is not difficult to find kidney cancer, as long as you do abdominal ultrasound Diagnosis.
