If liver cancer patients are diagnosed early and choose surgery in time, the success rate of surgery can reach 80%-100% and the surgical operation is relatively simple. For early stage patients, the survival time of 5 years after surgery can reach more than 30%, which means the treatment has been very successful, because 1-3 years after surgery is the high incidence of tumor recurrence and metastasis, therefore, regular follow-up and observation should be performed. Liver cancer patients should have liver enhancement CT and tumor marker examination every six months after surgery, and they should pay attention to monitor the changes of liver function indexes in general. The occurrence of liver cancer is mainly caused by chronic viral hepatitis that is not cured for a long time and liver cirrhosis. For middle-aged and elderly male patients, there are also some patients with alcoholic cirrhosis caused by long-term alcohol consumption, which eventually becomes cancerous. The treatment of liver cancer is a comprehensive treatment mainly based on surgery, and later on, chemotherapy or interventional treatment can also be chosen.
