E-cigarettes may raise lung and oral cancer risk

Many people use e-cigarettes believing that they do not have harmful effects on health. However, new research suggests that nicotine found in e-cigarettes and vaping products may increase the risk of lung and oral cancers. This finding comes from a medical study conducted in Australia.

Researchers at the University of New South Wales examined the health effects associated with e-cigarette use. As part of the study, they analyzed existing research on the subject and found evidence suggesting that e-cigarette use may also contribute to the development of cancer. The researchers investigated whether e-cigarettes could directly cause lung or oral cancer.

According to the researchers, this is the most comprehensive review conducted on the topic so far and indicates that e-cigarette use may increase the risk of cancer. They added that a review of all available research challenges the common belief that e-cigarettes do not pose a cancer risk.

The researchers noted that while their study is of high quality further research is needed to confirm these findings.

According to the team, many people assume that e-cigarettes help smokers quit tobacco and reduce their cancer risk, but the available evidence does not fully support that assumption. They stated that the current evidence is fairly strong though clinical trials involving humans will be necessary for definitive confirmation.

The study found that existing evidence suggests e-cigarette use may increase the risk of lung cancer by as much as four times. The findings of the study were published in the journal Carcinogenesis.
