Overview
- The Australian-led review, published Monday in the journal Carcinogenesis, concludes e‑cigarettes likely cause lung and oral cancer.
- Researchers report DNA damage, inflammation, and epigenetic changes in exposed cells that track with known cancer pathways.
- Animal experiments cited in the review found more lung tumors after aerosol exposure, including one study where 22.5% of mice developed cancer.
- Human biomarker studies show vapers absorb carcinogens and heavy metals such as lead, nickel, and antimony from some disposable devices.
- Long cancer latency and prior smoking blur near-term incidence data, yet Austria is tightening e‑liquid sales in April and Germany’s environment minister wants a ban on single‑use vapes.
