Liver cancer cannot be passed on to the next generation, it is not a hereditary disease. If liver cancer occurs in more than one person in the family, it is usually caused by viral infection. For example, hepatitis virus, which is transmitted horizontally. If there are hepatitis patients or hepatitis virus carriers in the family, then when family members have meals, gatherings and other group activities, they may infect others who are not sick, thus causing familial infection. There is also vertical transmission of hepatitis B and C viruses. Hepatitis B virus infected persons or carriers can transmit the virus to their newborns during labor and delivery. Newborns with incomplete development and low immune function are very susceptible to Hepatitis B virus infection, which can lead to hepatitis, cirrhosis and other diseases, and then transform into liver cancer. All the above cases are caused by viral infection, and family members often live together, so the chance of infection is higher, so it creates the illusion that this disease is hereditary, but liver cancer is not a hereditary disease.
