European studies on risks of hepatocellular carcinoma
While a causal link between hepatitis B and C and hepatocellular cancer has been known for a few decades, tobacco smoking, obesity, and alcohol consumption are common risk factors, albeit with lower relative risks, that also contribute to the development of the disease. In fact, there were many more Europeans with hepatocellular cancer who were smokers than carriers of hepatitis virus infections. Previous studies have not explored the contribution of each risk factor.
