Electronic cigarettes linked to higher cancer risk

Research findings from Sydney University

According to the study conducted at the University of New South Wales in Sydney and published in the journal Carcinogenesis, researchers carried out an extensive review of laboratory, animal, and clinical studies. They found biological indicators of DNA damage and oxidative stress, along with evidence of tumour development in animal experiments and the presence of compounds with carcinogenic properties in e-cigarette vapour.

Growing global concerns over vaping

The study also highlighted increasing global concern since the rise of electronic cigarettes in the early 2000s, after they were marketed as a less harmful alternative to traditional smoking and a tool to help quit smoking. However, their use has expanded significantly, especially among young people.

Dual use increases potential risks

Data suggests that some users engage in dual use of both electronic and traditional cigarettes, which may amplify potential health risks. Recent epidemiological studies link this pattern to a higher likelihood of lung cancer.

Broader health risks of smoking and vaping

Increasing medical reports and health studies suggest that both traditional smoking and electronic cigarettes pose a wide range of serious health risks. Traditional smoking is associated with cardiovascular disease, lung and respiratory cancers, weakened immunity, and long-term deterioration of lung function.

Emerging concerns over e-cigarettes

In contrast, electronic cigarettes are emerging as a growing concern, with evidence indicating that they contain chemicals that may cause cellular damage and oxidative stress. They are also potentially linked to an increased risk of certain cancers and respiratory diseases.
