Malignant tumor of liver generally refers to hepatocellular carcinoma, and how long one can live depends on the stage of hepatocellular carcinoma and whether there is distant metastasis, etc. Clinically, there is no specific survival time, and most of them take 5-year survival rate as the prognosis index, and its overall 5-year survival rate is 14.1% in China. The overall 5-year survival rate of liver cancer is 14.1% in China. The overall 5-year survival rate of liver cancer in China is only 14.1% due to the low early diagnosis rate, recurrence and metastasis after resection. A set of data from the Cancer Statistics Center of the National Cancer Institute of the United States shows that: the overall 5-year survival rate of liver cancer and intrahepatic cholangiocarcinoma is around 20%; if it is confined, the 5-year survival rate is 35%; if there is regional lymph node metastasis, the 5-year survival rate is around 12%; if there is distant metastasis, the 5-year survival rate is only around 3%. Therefore, once liver cancer is diagnosed, one should seek medical treatment as soon as possible. Early diagnosis and treatment of this disease can increase the survival rate of patients, achieve better prognosis and improve the quality of life.
