Scientists at New York University in the United States have found that the use of e-cigarettes increases the risk of lung cancer in rodents. The research results are published in the journal Proceedings of the National Academy of Sciences.
Experts found that in mice that were exposed to vapors for 54 weeks, 22.5 percent (9 out of 40 animals) developed adenocarcinoma of the lungs and 57.5 percent (23 out of 40 animals) developed urothelial hyperplasia of the bladder. This is in line with previous work that showed that e-cigarette smoking causes DNA damage in lung and bladder tissue.
While many studies confirm that vaping is safer than smoking regular cigarettes, there is conflicting evidence about the risks of using e-cigarettes.
Earlier it was reported about the findings of scientists at the University of Minnesota in the United States, who found that vapor from e-cigarettes can damage DNA in the cells of the oral cavity and cause the development of malignant tumors.
