The researchers say it's still not possible to quantify the exact risk of cancer caused by these products, however.
Scientists in Australia examined the medical literature on vaping, including case reports and animal studies. They found convincing evidence that e-cigarettes can cause cancer. Many questions remain, however, including the exact level of cancer risk posed by such products, the researchers say.
“Nicotine-based e-cigarettes are likely to be carcinogenic to humans who use them causing an indeterminate burden of oral cancer and lung cancer,” they wrote in their paper,E-cigarettes have emerged as an appealing alternative to tobacco-based cigarettes and other nicotine products over the past decade-and-a-half. But while many scientists havethat vaping is significantly safer than smoking, there’s been no shortage of debate and study over the possible health risks it might still have. The study researchers say most of this research has focused on the potential for vaping to become a “gateway” to smoking, particularly among children and young adults. They argue that considerably less attention has been paid to whether long-term use can also cause cancer. The researchers decided to conduct a “qualitative risk assessment” of the available evidence, analyzing relevant lab research, animal studies, and case reports of suspected cancers linked to vaping. All in all, they determined there was ample enough data to support a cancer link. Studies have indicated, for instance, that cell DNA can be harmed by the compounds or byproducts of e-cigarettes, including flavoring agents and certain metals. Biomarker studies have also suggested that vaping can damage and inflame oral and respiratory tissue in ways that could increase cancer risk. “To our knowledge, this review is the most definitive determination that those who vape are at increased risk of cancer compared to those who don’t,” study author Bernard Stewart, a cancer researcher at the University of New South Wales, in aThe researchers are quick to caution that the research so far cannot quantify the amount of cancer risk that vaping might cause. That will take long-term studies, they say, similar to the studies that helped conclusively prove smoking’s cancer-causing danger. It’s also worth noting at least some outside experts aren’t all that convinced by the researchers’ findings, while others argue that any cancer risk from vaping is likely to pale in comparison to smoking. “While it is clear that e-cigarettes expose users to harmful chemicals, which may lead to later disease, I would urge against sensationalization of evidence,” said Lion Shahab, co-director of the Tobacco and Alcohol Research Group at the University of College London, in acollected by the Science Media Center. This latest review “does not offer a ‘smoking gun’ that e-cigarettes cause oral or lung cancer.”vaping as a valuable tool to help people quit or cut down on their smoking. And it’s unlikely this review alone will significantly change those recommendations. “Because vaping is far less harmful than smoking, your health could benefit from switching from smoking to vaping. And you will reduce your risk of getting cancer,” While it’s best to avoid any nicotine habit in the first place, vaping’s probably still much safer over the long run, even if it can cause cancer.Logitech Wireless Keyboard and Mouse Combo Falls Under $25, a Budget Bundle Deal in the Final Hours of Spring SaleASUS Eye Care Monitor Hits an All-Time Low, Only Hours Left to Grab a 27″ Screen at a 15.6″ Budget Price on AmazonSamsung Bespoke AI Refrigerator Wants to Take the Stress Out of the KitchenA New Study Links Living Near Nuclear Plants to Higher Cancer Death RatesCould Poop Pills Be a Secret Weapon Against Cancer?Colorblind people might have a unique disadvantage in noticing an early warning sign of certain cancers, a new study suggests.
