A study in The Lancet Oncology estimates that 2.3 million cancer cases globally in 2024 are linked to infections, representing 12% of all diagnoses. This highlights that a substantial part of the global cancer burden is preventable through infection control. Historically, infectious diseases and oncology have been treated separately, but they are closely connected. Aggressive infection control strategies, including vaccination and treatment, can prevent millions of future cancer diagnoses. The bacterium H. pylori was the leading cause of infection-attributable cancers, accounting for 760,000 cases. Human Papillomavirus (HPV) followed closely, responsible for 750,000 cases. Hepatitis B virus (HBV) contributed 360,000 cases, while Epstein-Barr virus (EBV) and Hepatitis C virus (HCV) accounted for 260,000 and 160,000 cases, respectively. Over three-quarters of cancers attributable to infections occurred in low- and middle-income countries. Eastern Asia bore the largest burden, with 990,000 cases, or 42% of the global total. Higher rates were also observed in sub-Saharan Africa, Central and Eastern Europe, and Southeast Asia.
