Liver cancer embolization is a novel liver cancer treatment, which is a minimally invasive treatment, i.e., embolization agent and chemotherapy drugs are injected into liver cancer cells through the hepatic artery to cause ischemia and necrosis of liver cancer cells to treat liver cancer. This treatment is very important in the treatment of liver cancer and is also a major minimally invasive treatment modality. Liver cancer embolization and liver cancer intervention, also called TACE surgery, are minimally invasive procedures and are the preferred treatment for intermediate and advanced liver cancer. The survival rate of patients can reach more than 70% in 1 year and 30%-40% in 5 years, and if liver cancer below 5cm is treated by intervention, the 5-year survival rate can reach 30%-40%, which is very effective for patients with liver cancer.
