After radical surgical resection of early stage liver cancer, some patients can survive for more than 5 or 10 years, which is clinically called cure. Early stage liver cancer refers to tumors with a diameter of less than 3cm and the number of tumors not more than 3, which can usually be radically cured through surgery. Early-stage liver cancer usually has no obvious clinical symptoms and is discovered by patients during regular physical examination. It is usually seen in patients with chronic viral hepatitis, cirrhosis, long-term alcohol consumption or severe fatty liver. Survival rate of liver cancer patients is closely related to the recurrence of the tumor. Some patients recover well after surgery and have no recurrence, and their survival time is definitely longer. If the liver cancer recurs repeatedly after surgery or cannot be operated again, the survival time of these patients may be shorter. And it must be followed up closely to achieve early detection, early diagnosis and early treatment in order to achieve good therapeutic effect. It is possible to live for 10 years after surgery for early stage liver cancer. Therefore, regular checkup after liver cancer surgery is very important.
