Patients with liver cancer can have no symptoms in the early stage, and when it is in the middle or late stage, they will have pain in the liver area, decreased appetite, nausea, vomiting and so on. According to statistics, the annual mortality rate of liver cancer has reached 20.40 per 100,000 people, so early diagnosis and treatment are very crucial.
