WHO Finds 38% of 19 Million 2022 Cancer Cases Were Preventable
3 articles · Updated · ScienceAlert · May 22
Nearly 7.2 million of the 19 million new cancer cases recorded worldwide in 2022 were tied to 30 modifiable risk factors, according to a WHO analysis published in Nature Medicine.
Smoking was the biggest preventable driver, linked to 15% of all cancers globally and 23% in men; alcohol ranked next at 3.2%, or about 700,000 cases.
Lung, stomach and cervical cancers made up nearly half of preventable cases, while infections accounted for about 10% overall and HPV was the largest preventable cause among women.
Air pollution showed sharp regional effects, contributing to about 15% of lung cancer cases in women in East Asia and roughly 20% in men in Northern Africa and Western Asia.
WHO said the findings give governments a first global map of preventable cancer risks, underscoring the need for stronger vaccination, anti-smoking and environmental health measures.
If lifestyle causes 38% of cancers, what hidden factors are driving the majority of cases we cannot yet prevent?
We can prevent nearly 40% of cancers. Why are proven solutions like vaccines and health policies failing to reach millions worldwide?
A common stomach bacteria is a top cancer cause. Could mass eradication be the key to preventing hundreds of thousands of deaths?
Global Cancer Prevention 2026: Key Findings, Disparities, and Strategies to Halt a Projected 50% Rise by 2045
Overview
The 2026 global cancer prevention report highlights an urgent need for effective strategies as cancer cases are expected to rise by over 50% by 2045. Building on a 2022 WHO/IARC assessment, the report shows that many cancer cases can be prevented through targeted interventions. By addressing preventable causes, such as behavioral, environmental, and infectious risks, there is a powerful opportunity to reduce the global cancer burden. This comprehensive analysis provides a pivotal, data-driven approach to guide global prevention efforts and emphasizes that focused action can make a significant impact on future cancer rates.
