Study finds surprising new link between vaping and cancer
A new review suggests nicotine-based e-cigarettes likely cause lung and oral cancers, even independent of smoking history.Summary
A recent review published in Carcinogenesis, led by UNSW Sydney, indicates that nicotine-based e-cigarettes are likely to cause cancers of the lung and oral cavity. The study deliberately excluded dual users (those who both smoke and vape) to assess the independent cancer risk of vaping. Researchers examined clinical findings, animal experiments, and laboratory research, finding carcinogenic compounds in e-cigarette aerosols, DNA damage in users, and increased cancer rates in mice exposed to the aerosols. Evidence suggests vaping exhibits all ten 'key characteristics of carcinogens,' indicating a complex chemical exposure. While long-term population studies are still needed, the authors argue the existing evidence warrants a public health warning and tighter regulation of e-cigarettes, emphasizing that waiting for definitive proof could lead to preventable cancers.
