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