Under normal circumstances, contact with liver cancer patients is generally not contagious, as liver cancer is a malignant tumor, and malignant tumors are not contagious, so normal contact will not lead to liver cancer infection. Some liver cancer patients are caused by viral infection, for example, hepatitis B virus infection may lead to liver cancer, so we should pay attention to it in our daily life, because hepatitis B virus may be contagious. However, the infection is mainly transmitted through blood transmission or vertical transmission, etc. Usually, normal contact will not lead to the transmission of hepatitis B virus.
