Lung cancer after one year of exposure to electronic cigarette smoke for 22.5% of guinea pigs in an American study

Exposure to smoke resulting from the use of electronic cigarettes has led to lung cancer in some of the laboratory mice tested in a study published Monday in the scientific journal Proceedings of the National Academy of Sciences, quoted by the Xinhua Agency.

A team of researchers from New York University's Faculty of Medicine (NYU) found that nine of the forty (22.5%) of mice exposed for 54 weeks to smoke resulting from nicotine-e-cigarettes developed cancer pulmonary.

At the same time, 23 of the mice tested developed bladder hyperplasia, genetic changes that can lead to abnormal tissue growth seen in cancer.

By comparison, only one of the 17 laboratory mice exposed to smoke from nicotine-free electronic cigarettes developed hyperplasia.

Earlier, the researchers claimed that the chemicals added during tobacco processing turn nicotine into nitrosamine, a carcinogen for mice and humans, Xinhua notes.

Although electronic cigarettes contain 95% less chemicals, the new study has shown that mammalian cells can react directly to nicotine resulting in nitrosamine and subsequently cause DNA damage, writes Agerpres.

"Our next step on this line is to increase the number of mice studied to shorten and extend the exposure time of electronic cigarettes and then analyze the genetic changes caused by the smoke from electronic cigarettes," explained one of the study's co-authors, Herbert Lepor from NYU.
