What Is Hepatocellular Carcinoma?
Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer (a type of cancer that starts in the liver). HCC begins in the main type of liver cell, a hepatocyte. It is most common in people with chronic liver diseases such as cirrhosis caused by hepatitis B or hepatitis C.
Hepatocellular carcinoma (HCC) is treated at Dana-Farber Brigham Cancer Center Liver Cancer Center.
Risk Factors for Hepatocellular Carcinoma
Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn't mean that you will not get cancer. People who think they may be at risk should discuss this with their doctor.
Risk factors for hepatocellular carcinoma include:
- Having chronic hepatitis B (HBV) or chronic hepatitis C (HCV). The risk is even higher for people with both HBV and HCV, or people who have the hepatitis virus along with other risk factors listed below.
- Cirrhosis, a disease where healthy liver tissue is replaced by scar tissue which blocks the flow of blood through the liver and keeps it from working as it should. Chronic alcoholism and chronic hepatitis infections are common causes of cirrhosis.
- Heavy alcohol use.
- Aflatoxin B1, poison from a fungus that can grow on foods.
- Cigarette smoking.
