Hepatocellular carcinoma will lead to damage of liver function, and the early stage of its development usually does not cause obvious symptoms. Once the disease develops and causes related symptoms, such as abdominal mass, pain, loss of appetite, fatigue, weight loss, nausea and vomiting, etc., it often represents that the condition of the patient has already progressed to the middle or late stage, and if not treated in time, the spread of metastasis of the cancer cells may jeopardize the lives of the patients.
