If Hepatitis B is treated early and becomes chronic, the survival time is longer at 20~30 years, but if it turns into cirrhosis, liver cancer, etc., the life expectancy is 1~2 years. If hepatitis B is detected early, combined with early scientific treatment, the general survival time is longer, under the premise of good control of the disease can have a survival time of 20~30 years. Elderly people generally have a natural life expectancy and are relatively unaffected by the hepatitis B virus. If the disease is detected late or serious complications such as cirrhosis, liver cancer, hepatic encephalopathy, etc. have already occurred by the time the disease is detected, the survival time is relatively short. The general survival rate within 5 years is below 30%, and those with more serious conditions may expect a survival time of 1 to 2 years. The details need to be determined according to your own situation and after consulting your doctor.
