Scientists Warn: Vaping Likely Causes Cancer
A new scientific review suggests vaping poses a serious cancer risk due to biological changes and harmful chemicals in e-cigarette aerosols.Summary
A comprehensive review led by UNSW Sydney, published in Carcinogenesis, indicates that vaping is likely to cause cancer. Researchers analyzed human studies, animal experiments, and lab research, finding that e-cigarette aerosols contain substances known to damage DNA and disrupt cellular processes, including volatile organic compounds and trace metals. While the exact cancer risk is still unknown and requires longer-term studies, the evidence consistently points towards an increased risk of lung and oral cancer for vapers. The study highlights that many vapers continue to smoke cigarettes, leading to an even higher cancer risk for those in 'dual-use' situations. Researchers draw parallels to the delayed recognition of smoking's harms and urge prompt action regarding vaping, noting that e-cigarettes were initially marketed as a safer alternative but may be repeating a pattern of overlooked early warning signs.
