An analysis suggests that one in eight cancer cases globally are linked to infectious causes.

## AI-generated summary

New research from the World Health Organization indicates that approximately 12% of all cancer cases globally in 2024, totaling 2.3 million, were linked to infections. Five main pathogens—Helicobacter pylori, HPV, hepatitis B, Epstein\-Barr virus, and hepatitis C—are responsible for the majority of these infection\-related cancers, which can lead to over 20 types of cancer. The findings underscore the significant role of infection control and prevention in reducing cancer rates, particularly in low\- and middle\-income countries.
