Nicotine Vaping Causes Lung Cancer in Mice, Study Finds

Nicotine Vaping Causes Lung
Cancer in Mice, Study Finds.
A recent study by New York University
has found a pattern of lung cancer in
mice exposed to e-cigarette vapor. .
Over a 54 week period, 40 mice received
the vapor equivalent of someone who’s
smoked e-cigarettes for three to six years. .
22.5 percent developed lung cancer and 57.5 percent
developed pre-cancerous lesions in their bladders.
An additional 20 mice,
who only received vapor
free of nicotine, were
found to be cancer free. .
According to the study’s lead professor,
Moon-shong Tang, these results prove that
e-cigarette vapor is likely a human carcinogen. .
The carcinogenic mechanism is via production
of nitrosamines, the proven human carcinogens.
So, the probability that e-cigarette vapor is a
human carcinogen is high, Moon-shong Tang, to Axios.
In a previous study, Tang also found that
electronic cigarette smoke induced DNA
damage and inhibited DNA repair in mice.
