which type of hepatitis is responsible for 50 to 76 of all patients with liver cancer
Liver cancer Viral infection with either hepatitis C virus (HCV) or Hepatitis B virus (HBV) is the chief cause of liver cancer in the world today, accounting for 80% of hepatocellular carcinoma (HCC).[14][15][16] The viruses cause HCC because massive inflammation, fibrosis and eventual cirrhosis occurs within the liver. HCC usually arises after cirrhosis, with an annual incidence of 1.7% in cirrhotic HCV-infected individuals.[17] Around 5-10% of individuals that become infected with HBV become chronic carriers, and around 30% of these acquire chronic liver disease, which can lead to HCC.[14] HBV infection is also linked to cholangiocarcinoma.[18] The role of viruses other than HCV or HBV in liver cancer is much less clear, although there is some evidence that co-infection of HBV and hepatitis D virus may increase the risk of HCC.[19]
