New Study Warns Vaping May Increase Risk of Lung and Oral Cancer
A new review by researchers at UNSW Sydney has raised fresh concerns about the safety of vaping, suggesting it could increase the risk of both lung cancer and oral cancer.
The research team analysed a growing body of international evidence on e-cigarettes and their impact on human health. Their findings indicate that while vaping is often promoted as a safer alternative to smoking, it is not without significant risks—particularly for the respiratory system and mouth.
What the study found
According to the review, chemicals found in e-cigarette vapour can damage cells in the lungs and oral cavity. Some of these substances are known carcinogens, meaning they have the potential to cause cancer over time.
Researchers highlighted that repeated exposure to these chemicals may lead to:
- Inflammation and damage in lung tissue
- Changes to cells in the mouth that could develop into cancer
- Increased long-term health risks, especially for regular users
Concerns for young people
The study also raised concerns about the rising popularity of vaping among young people. Researchers warned that early and prolonged exposure could increase the likelihood of developing serious health conditions later in life.
A spokesperson from the research team said the perception that vaping is “harmless” needs to be challenged, particularly in public health messaging aimed at teenagers and young adults.
Implications for health and social care
For professionals working in health and social care, the findings underline the importance of:
- Educating service users about the risks of vaping
- Supporting smoking and vaping cessation programmes
- Monitoring symptoms linked to respiratory or oral health issues
A call for further research
While the review adds to growing evidence about the dangers of vaping, researchers stressed that more long-term studies are needed to fully understand the extent of the risks.
Key message
Although vaping may still be less harmful than traditional smoking, this latest review suggests it is far from risk-free. Health professionals are being encouraged to take a cautious approach and ensure individuals are fully informed about the potential dangers.
