What makes some people with hepatitis c more likely to get liver cancer?

Cirrhosis: Hepatitis c commonly causes chronic liver disease. Over time, if untreated, and with ongoing inflammation, can lead to scarring (cirrhosis). Hep c patients with cirrhosis are at increased risk for liver cancer. Goals of rx are to get rid of virus, stop the inflammation, prevent the scarring, and prevent cancer as well as liver failure.

Bad disease control: Patients who are not well controlled by treatment, who continue to have liver damages due to the virus, and/or other factors such as IV drug use, alcohol, will have a higher chance to progress to cirrhosis, and liver cancer. Also, high fat diet can increase injury to the liver and thus more risk for cancer.
