Patients with liver cancer will have obvious coma in the last few days, which is commonly known as hepatic coma. As the condition evolves, liver function indexes will deteriorate, because liver cancer patients usually have alcoholic liver due to the combination of chronic viral hepatitis and a history of drinking alcohol for many years. The patient will also show obvious yellow staining of sclera, dark color, pale conjunctiva, abdominal distension, usually accompanied by a large amount of ascites, and positive mobile turbid tone on percussion, and fever and secondary gastrointestinal hemorrhage in the later stage, which will be manifested as black stools, blood in the stools, and even vomiting of blood in serious cases, even inducing the emergence of asphyxiation. The occurrence of liver cancer is mainly due to personal factors, and some of them have obvious family genetic history, while early diagnosis should be timely selected for surgical treatment.
