In the past, due to the limitation of medical technology level and economic conditions and many other factors, people were afraid of talking about liver, and if liver cancer was diagnosed, it would mean death. However, in recent years, with the improvement of medical technology, medical equipment and economic level, the mortality rate of liver cancer patients has gradually decreased. According to clinical statistics, for small hepatocellular carcinoma, that is, hepatocellular carcinoma less than 5cm in diameter, the 5-year survival rate can reach more than 80% after surgical resection and postoperative interventional treatment. Nowadays, medical examination equipment, such as B-ultrasound and CT, can detect liver cancer smaller than 1cm. Therefore, for liver cancer, if it can be detected early, diagnosed early and treated early, it can be effectively cured without the fear of death.
