The hepatitis B virus is classified as carcinogenic to humans. Chronic hepatitis B infection is the most common etiological agent of hepatocellular carcinoma worldwide. There is evidence that the hepatitis B virus is also associated with other types of tumors, such as intrahepatic cholangiocarcinoma, pancreatic ductal adenocarcinoma, B-cell lymphoma, and others. However, there is effective prevention of hepatitis B in the form of vaccination. The vaccine against this infection was the first to be shown to be effective in preventing tumors and is considered a great success in the clinical chemoprevention of hepatocellular carcinoma, which is why it is part of national vaccination programs in children (who have the worst prognosis). Hepatitis B poses a risk to cancer patients treated with chemotherapy, so it is advisable to provide them HBV screening before treatment and, as a result, to protect patients from infection with either vaccines or antivirals.
