WashU Medicine Expert Says Simple Steps Can Help Prevent Liver Cancer

St. Louis, Mo. (KFMO) - Liver cancer may not get as much attention as other cancers, but health experts say simple lifestyle changes and regular screenings can greatly reduce the risk...

According to researchers with Washington University School of Medicine in St. Louis, the liver quietly performs many vital functions in the body, including removing toxins, storing energy and supporting the immune system. Because of its importance, doctors say protecting liver health should be a priority.

Yikyung Park, a cancer researcher and professor in the Division of Public Health Sciences at WashU Medicine, says liver cancer is especially dangerous because it often receives less public attention than other forms of cancer.

Park says major risk factors for liver cancer include heavy alcohol use, hepatitis B and hepatitis C infections, cirrhosis of the liver, smoking, obesity, diabetes and fatty liver disease. Many of those conditions can overlap and increase a person’s overall risk.

Despite those concerns, Park says liver cancer is often preventable with regular medical care and healthier lifestyle choices.

Doctors recommend adults receive screening tests for hepatitis B and hepatitis C, since many infected people may not show symptoms. Hepatitis C can often be treated successfully, while treatments for hepatitis B can help limit liver damage and reduce cancer risk.

Health experts also encourage vaccination against hepatitis B, which they say is a safe and effective way to prevent infection.

Researchers say limiting alcohol use, or avoiding alcohol entirely, can significantly reduce the risk of liver disease and liver cancer. Maintaining a healthy weight through diet and physical activity can also help prevent fatty liver disease and diabetes, both of which are linked to liver cancer.

Smoking remains another major risk factor. Experts encourage smokers to seek help quitting through programs such as Smokefree.gov and 1-800-QUIT-NOW.

People already diagnosed with liver disease are urged to see a doctor regularly, since ongoing monitoring may help detect cancer earlier when it is more treatable.

A recent international report published in The Lancet estimated that about 60 percent of liver cancer cases worldwide could be prevented through healthier behaviors and medical prevention efforts.
