IARC: 12% of 2024 cancer cases linked to infections; five pathogens dominate

A new IARC study attributes 2.3 million (12%) of 2024 cancer cases worldwide to infections, with five pathogens (likely HPV, H. pylori, hepatitis B/C, EBV) driving most cases. The finding underscores the preventive potential of vaccination and antimicrobial treatment, though the study's methodology and country-level breakdowns remain to be detailed. This matters for global health policy and resource allocation in cancer prevention.
