The number of years to live for hepatic malignant tumor is usually related to the type of pathology, stage of disease, and effective treatment methods, and there are large individual differences, so it cannot be generalized. Hepatic malignancy is a common type of malignant tumor in the digestive system. The main symptoms of patients in the early stage are abdominal distension, abdominal pain, jaundice, and possibly diarrhea. Patients with milder disease and early detection may survive for more than 3-5 years or even longer if they can undergo surgery for radical treatment. Patients with more severe disease and late detection may not be able to do surgical treatment, and most patients do not survive for long, within 1-2 years more often. And patients with intermediate to advanced disease may survive for about 3 months to 6 months. In conclusion, general patients can make clinical diagnosis of liver cancer through liver enhancement CT, combined with tumor index methemoglobin elevation greater than 400μg/L for 1 month continuously, and early detection and early treatment.
