Key Points:

A recent review by Australian scientists concludes that nicotine-based e-cigarettes are likely carcinogenic, potentially increasing the risk of oral and lung cancers in users.
The study analyzed medical literature, lab research, animal studies, and case reports, finding evidence that compounds in e-cigarettes can damage DNA and inflame tissues linked to cancer development.
Researchers caution that the exact level of cancer risk from vaping remains unclear and requires long-term studies similar to those conducted for smoking.
Some experts urge caution against overstating the findings, noting that while e-cigarettes expose users to harmful chemicals, definitive proof of cancer causation is lacking and risks are likely lower than smoking.
Health organizations continue to support vaping as a harm reduction tool for smokers, emphasizing that switching from smoking to vaping can reduce overall cancer risk despite potential risks associated with vaping itself.
