Surprising culprit tied to 1 in 8 cancer cases worldwide, major study reveals

About one in eight new cancer cases worldwide in 2024 — 2.3 million cases — have been linked to infections, according to a new analysis from the International Agency for Research on Cancer (IARC).The researchers identified 12 specific infections that were linked to human cancer cases, including Helicobacter pylori (H.pylori), human papillomavirus (HPV), hepatitis B virus (HBV), hepatitis C virus (HCV), Epstein–Barr virus (EBV), Kaposi sarcoma-associated herpesvirus, Schistosoma haematobium, HTLV-1, Opisthorchis viverrini, Clonorchis sinensis, Merkel cell polyomavirus and HIV.The following five infections contributed to nearly all the global cases.POPULAR DAILY DRINKING HABIT COULD NEARLY TRIPLE RISK OF DEADLY CANCER, MAJOR STUDY FINDSAbout one in eight new cancer cases worldwide in 2024 — 2.3 million cases — were linked to infections, according to a new analysis from the International Agency for Research on Cancer (IARC).

The findings were published in The Lancet Oncology on Sept.28.The study had several limitations, the researchers acknowledged.Because the study used population-level estimates rather than tracking individual patients over time, the results depended on the quality of available cancer data in each country.Additionally, it only included infections already prov...
