Another setback for vapes? Using the devices can increase the risk of oral cancer as much as cigarettes do, study finds
Source: www.dailymail.co.uk Author: Cassidy Morrison, Senior Health Reporter DailyMail.com Using a vape causes cancer-linked DNA damage to the mouth at the same rate as using a cigarette does, study finds. The latest study from researchers at the University of Southern California (USC) further pokes holes in the notion that vaping e-cigarettes such as Juul and PuffBar devices are a healthier alternative to smoking. Vapers who regularly use e-cigarettes saw just as much damage to DNA in their mouths as smokers of regular tobacco cigarettes, raising the specter of chronic diseases including cancer. Flavor pods in particular were the most dangerous. Cancers are caused by such DNA damage, also referred to as gene mutations that, over time, may stop working normally or grow out of control and become cancerous. This is not the first study to come to this conclusion. Canadian researchers found that mice exposed to flavored vapes consistently suffered serious cellular and molecular damage to their lungs. Dr Ahmad Besaratinia, senior author of the study and public health experts at USC, said: ‘For the first time, we showed that the more vapers used e-cigarettes, and the longer they used them, the more DNA damage occurred in their oral cells.’ Smoking exposes the cells coating the inside of the mouth, the airways, and the lungs to dozens of powerful chemical carcinogens. The cells in parts of the body that are directly exposed to smoke are damaged most acutely, with 150 mutations found to occur in each lung cell within one [...]
