Researchers emphasized that precautionary measures should be taken immediately.
A comprehensive scientific study conducted in Australia has raised alarming concerns over e-cigarettes (vaping), suggesting that their use could be associated with lung and oral cancers.
Researchers emphasized that precautionary measures should be taken immediately rather than waiting for long-term, definitive evidence.
The study, overseen by scientists at University of New South Wales, reviewed a wide range of scientific reports, human case studies, laboratory experiments, and animal studies published between 2017 and 2025. Its primary aim was to determine whether nicotine-containing e-cigarettes could contribute to cancer development.
Findings indicate that vaping induces early biological changes strongly linked to cancer, including DNA damage and increased inflammation.
The study, published in the renowned journal Carcinogenesis, highlights that these changes precede cancer and are potentially hazardous.
Experts explained that inhaling e-cigarette vapors can cause significant cellular alterations in the mouth and lungs.
Although e-cigarettes are relatively new and long-term human data remain limited, some cases have emerged in which individuals who only vaped without smoking traditional cigarettes were diagnosed with oral cancer.
Animal studies also showed that mice exposed to e-cigarette vapors developed more lung tumors, though researchers caution that these findings cannot be directly extrapolated to humans.
