E-cigarettes could raise risk of cancer and heart disease, warn scientists
E -cigarette vapour could raise the risk of developing of cancer and heart disease by damaging DNA in as little as 10 years, a new study suggests.
Researchers from New York University School of Medicine said while it was clear that vaping was less harmful than smoking, it was still ‘dangerous’ for non-smokers and should not be promoted as safe.
The scientists looked for mutations to DNA in animals, as well as human lung, bladder and heart cells, when exposed to e-cigarettes for the equivalent of 10 years.
They found that in comparison to filtered air, e-cigarette vapour damages DNA and also prevents the genetic code from repairing itself.
Writing in the Proceedings of the National Academy of Sciences, the authors conclude: “It is therefore possible that e-cigarette smoke may contribute to lung and bladder cancer, as well as heart disease, in humans.
