Hepatocellular carcinoma (HCC) is the most related type of primary liver cancer. Hepatocellular carcinoma occurs most often in people with chronic liver diseases, like cirrhosis caused by hepatitis B or hepatitis C infection. The risk of hepatocellular carcinoma, the most common category of liver cancer, is larger than in people with long-term liver diseases.
It's also higher if the liver is scarred by infection with hepatitis B or hepatitis C. Hepatocellular carcinoma is most common in people who drink large amounts of alcohol and who have an accumulation of fat in the liver.
