Global Study: Infections Cause 12% of New Cancers, Highlighting Preventable Risks
A new study in The Lancet Oncology estimates that 2.3 million new cancer cases worldwide in 2024, or 12% of all diagnoses, were caused by infectious agents. The five most significant pathogens are Helicobacter pylori, human papillomavirus (HPV), hepatitis B, Epstein-Barr virus, and hepatitis C. Researchers emphasize that many of these cancers are preventable through vaccination, screening, and treatment, though access to these interventions remains uneven globally.
