How many liver cancer patients show evidence of hepatitis infection?

Hepatitis infections, particularly chronic infections with hepatitis B virus (HBV) or hepatitis C virus (HCV), are significant risk factors for the development of liver cancer. Chronic hepatitis infections can lead to inflammation and damage to the liver over time, increasing the likelihood of liver cancer. The relationship between hepatitis and liver cancer is well-established: Hepatitis B Virus (HBV): Chronic infection with HBV is a major risk factor for liver cancer. Individuals with chronic HBV infection have a higher risk of developing liver cirrhosis, which can progress to liver cancer. Hepatitis B vaccination is a preventive measure to reduce the risk of HBV-related liver cancer. Hepatitis C Virus (HCV): Chronic infection with HCV is another significant risk factor for liver cancer. Similar to HBV, chronic HCV infection can lead to liver cirrhosis and increase the risk of liver cancer. Antiviral medications are available to treat chronic HCV infection and may reduce the risk of liver cancer in some cases. The prevalence of hepatitis infection in liver cancer patients can vary depending on geographic regions, as the prevalence of hepatitis infections is not uniform worldwide. In areas with high rates of hepatitis infections, a substantial proportion of liver cancer cases may be attributed to chronic hepatitis.
