Among the most effective ways to reduce the risk of developing liver cancer is to avoid exposure to the hepatitis B and C viruses. Vaccines for hepatitis B are commonly available for children and adults. If you are at risk for hepatitis B or C infection, consider undergoing a screening test.
If you have chronic hepatitis B, you might be a candidate for antiviral therapy, which can slow down progression of liver disease and decrease (although not eliminate) the risk of liver cancer.
Undetected and untreated, however, infection with the hepatitis B virus can lead to cirrhosis, liver failure, and cancer. While there is no vaccine for hepatitis C, appropriate treatment can eliminate the virus in up to 80 percent of individuals. Even more-effective treatments for hepatitis B are being explored.
You can also lower your risk for developing liver cancer by following a healthy diet with limited alcohol and getting regular physical exercise.
