The advantages of liver cancer intervention are that it is less traumatic, with exact efficacy, and can be repeated. The disadvantage is that it is difficult to operate and cannot be cured radically. 1. Liver cancer interventional therapy is the technique of applying interventional technology in the arteries supplying blood to the tumor, which is one of the most commonly used non-surgical means for treating liver cancer. It is widely used in the palliative treatment of patients with relatively small liver injury but cannot be surgically resected for liver cancer, which can significantly prolong the survival period. Repeatable treatment, little trauma, usually can get out of bed in a day or so. 2. The disadvantage is that it is difficult to operate, and often causes arterial entrapment or rupture and bleeding due to severe vascular atherosclerosis and improper operation. Common complications include post-chemoembolization syndrome, liver abscess, gastrointestinal bleeding and so on. In the process of interventional therapy for liver cancer, it is necessary to weigh the harms and benefits to the human body, and the specific situation should be analyzed according to the condition under the guidance of doctors.
