Researchers find strongest evidence yet that vaping likely causes cancer
A new review finds strong evidence that vaping likely causes oral and lung cancers, based on carcinogenic effects observed in vapers.Summary
Researchers have found the strongest evidence to date suggesting that vaping likely causes oral and lung cancers. While long-term studies are still needed, a comprehensive review of existing research reveals that the aerosol inhaled from vapes contains chemicals demonstrating almost all ten key characteristics of carcinogens identified by the World Health Organization. Analyses of blood and urine from vapers show absorption of cancer-linked chemicals, including carcinogenic metals and organic compounds. Evidence also includes DNA mutations, changes in cancer biomarkers, and studies on mice demonstrating lung cancer caused by vape aerosols. The shift in research conclusions from 2017-2019, where insufficient evidence existed, to 2024-2025, where concerns are rising, highlights the growing body of evidence. Further research is crucial to determine the extent of cancer cases attributable to vaping and to enable early detection and prevention.
