 The study assesses the causal involvement of carcinogenic infectious agents in different cancer types for the year 2012. It considers 10 such agents, including helicobacter pylori, human papillomavirus, hepatitis B virus, and hepatitis C virus. The study estimates that 2.2 million new cancer cases in 2012 were attributable to carcinogenic infections, with the most important infectious agents being helicobacter pylori, human papillomavirus, hepatitis B virus, hepatitis C virus, and epsteinbar virus. The study also finds that the AFs for infection varied by country and development status, with some countries in Sub-Saharan Africa having higher AFs than developed countries. The study suggests that reducing the burden of cancer caused by infections is possible through population-based vaccination and screen-entry programs.
