People who vape suffer similar changes to their DNA as smokers who develop cancer, researchers have revealed.
Scientists at University College London analysed samples of cheek cells from vape users and compared these with those from cigarette smokers. Both groups had similar changes to the DNA of cells in their mouth.
These changes were, in turn, linked to the future development of lung cancer in smokers.
The authors of the study, published in the journal Cancer Research, said the findings did not prove e-cigarettes cause cancer but show that “the devices might not be as harmless as originally thought”.
It is the first major study to draw a link between e-cigarettes and an increased risk of
