Clinically, there is no such thing as hepatitis B liver cancer, only the term liver cancer. the fact that an 80 year old man has never had symptoms of hepatitis B does not mean that he does not have it. Therefore, when liver cancer appears at this time, it is considered that it may be caused by Hepatitis B or newly infected Hepatitis B, but it is not a direct cause of Hepatitis B liver cancer.
Generally, there are 3 types of viral hepatitis related to liver cancer: hepatitis B, C and D. Hepatitis B is more closely related to liver cancer. If an 80-year-old man has not been tested for hepatitis B before, then the hepatitis B virus may be present in his body, but there are no symptoms associated with hepatitis B. When the disease progresses to a certain level and becomes serious, it may cause hepatocellular carcinoma. When the disease progresses to a certain degree and becomes serious, liver cancer, only then the corresponding symptoms appear, through the examination found to progress to cancer.
In addition, there are other causes of liver cancer, such as hepatitis C and D. Therefore, liver cancer in an 80-year-old man may also be caused by other viral hepatitis, which needs to be clarified through further examination.
