Liver cancer is the third most common malignant tumor after stomach cancer and esophageal cancer in terms of mortality rate. The symptoms are not obvious in the early stage, but mainly manifest as liver pain, weakness, emaciation, jaundice and ascites in the late stage. The main symptoms are as follows: 1. significant loss of appetite, abdominal stuffiness, indigestion, sometimes nausea and vomiting; 2. vague pain in right upper abdomen, persistent or intermittent pain in liver area, sometimes aggravated by position change; 3. general weakness, emaciation, unexplained fever and edema; 4. jaundice, ascites, skin itching; 5. often manifested as rhinorrhea, subcutaneous bleeding, etc. Some typical symptoms of hepatocellular carcinoma will only occur when the disease progresses to the middle and late stage, and by then the opportunity of surgery is often lost, so the usual self-examination is very important. When fatigue and weakness cannot be relieved, it is likely to be an omen of liver disease; a dull feeling in the heart fossa, or a dull pain in the upper right side of the abdomen, a feeling of pressure and discomfort, weight loss, unexplained fever and jaundice, you should go to hospital for examination as soon as possible.
