Smoking

Smoking by itself may not cause liver cancer, but it dramatically increases the risk, especially in people who have other risk factors, such as chronic hepatitis B or C infections. It is possible that cancer-causing chemicals in cigarettes cause further damage to liver cells that are already at risk for cancer because of chronic hepatitis B or C infections.
