The survival time after interventional treatment is uncertain and the prognosis of treatment varies with different tumor types. It may be several years or less than a year. For example, after interventional treatment for liver cancer, there are also those who survive for more than 3 years or 5 years, but there are also those who survive for less than half a year, so the prognosis of treatment is different for different patients and can only be seen while treatment. Interventional therapy is divided into minimally invasive interventional therapy for tumor vascularity and other non-vascular interventional therapy for tumor, such as radiofrequency ablation, radioactive particle implantation and so on. Vascular interventional therapy is the most widely used, mainly percutaneous vascular puncture for selective vascular cannulation and placing the catheter in the target vessel to complete the treatment of tumor and tumor-related lesions, and hepatic artery chemoembolization interventional therapy for hepatocellular carcinoma is the most used.
