What happened
Vaping is likely to cause lung and oral cancer, researchers have found, as they urged regulators to act now rather than wait decades for a definitive level of risk.
Why it matters
Cancer researchers led by UNSW in Sydney analysed reviews of evidence from animal studies, human case reports and laboratory research published between 2017 and 2025, in one of the most detailed assessments to date of whether nicotine e-cigarettes could cause…
Common ground
There are early warning signs in the body strongly linked to cancer risk, including DNA damage and inflammation, co-author Adjunct Prof Bernard Stewart said.
Perspective signals
No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
Follow-up questions
- What concrete event or decision sits underneath the headline: Vaping likely to cause lung and oral cancer, Australian researchers find in new review of evidence?
- What evidence would most clearly confirm or weaken the claim that Calvin Cochran, a research fellow at the University of Otago’s department of public health in New Zealand, said nearly 8,000 studies were ultimately assessed to reach that conclusion, despite earlier warning signs that were often dismissed or discredited, including by doctors?
- What should readers watch for in the next update to know whether the story is changing?

Claim 1: “Calvin Cochran, a research fellow at the University of Otago’s department of public health in New Zealand, said nearly 8,000 studies were ultimately assessed to reach that conclusion, despite earlier warning signs that were often dismissed or discredited, including by doctors.”
PENDING
This claim was extracted as a checkable statement from the article. eFinder labels it pending based on the available evidence and source context shown below.
Claim 2: “Prof Becky Freeman, a tobacco control researcher with the University of Sydney, said: This study is the first to assert that there is likely an increased cancer risk for people who vape, compared to people who do not vape.”
PENDING
This claim was extracted as a checkable statement from the article. eFinder labels it pending based on the available evidence and source context shown below.
Claim 3: “There are early warning signs in the body strongly linked to cancer risk, including DNA damage and inflammation, co-author Adjunct Prof Bernard Stewart said. The review, published in the journal Carcinogenesis on Tuesday, found vaping is associated with these pre-carcinogenic changes.”
INSUFFICIENT EVIDENCE
No evidence found in web search, cross-references, or Wikipedia to support the claim about DNA damage and inflammation.
Claim 4: “Prof Stephen Duffy, from Queen Mary University London, said it would be an overinterpretation to say vaping is as harmful as smoking off the back of the research, as vaping does not involve exposure to the combustion products in smoking which have massive carcinogenic effects.”
PENDING
This claim was extracted as a checkable statement from the article. eFinder labels it pending based on the available evidence and source context shown below.
Claim 5: “Lead author of the study, epidemiologist Associate Prof Freddy Sitas, said it took 100 years of emerging and growing evidence before the US Surgeon General recognised smoking as a cause of lung cancer in 1964.”
PENDING
This claim was extracted as a checkable statement from the article. eFinder labels it pending based on the available evidence and source context shown below.
Claim 6: “The review included case reports from dentists who noticed oral cancer in people who had only vaped and who had never smoked.”
INSUFFICIENT EVIDENCE
No evidence found in web search, cross-references, or Wikipedia to confirm dentist-reported cancer cases.
Claim 7: “We determined e-cigarettes are likely to cause lung cancer and oral cancer, though we cannot say how great that burden will be, he said.”
INSUFFICIENT EVIDENCE
No evidence found in web search, cross-references, or Wikipedia to confirm the quote about cancer likelihood.
Claim 8: “Cancer researchers led by UNSW in Sydney analysed reviews of evidence from animal studies, human case reports and laboratory research published between 2017 and 2025, in one of the most detailed assessments to date of whether nicotine e-cigarettes could cause cancer.”

Claim 10: “Australian laws that limit vapes to pharmacy-only access for people who are using them to quit smoking are the right approach.”
PENDING
This claim was extracted as a checkable statement from the article. eFinder labels it pending based on the available evidence and source context shown below.
Claim 11: “The review, published in the journal Carcinogenesis on Tuesday, found vaping is associated with these pre-carcinogenic changes.”
INSUFFICIENT EVIDENCE
No evidence found in web search, cross-references, or Wikipedia to confirm the journal publication claim.
Claim 12: “It also examined animal studies, and Stewart referred to a study that found mice exposed to e-cigarette vapour developed lung tumours at greater rates than unexposed mice, although such findings do not necessarily translate directly to humans.”
INSUFFICIENT EVIDENCE
No evidence found in web search, cross-references, or Wikipedia to support the mouse study claim.
Claim 13: “The review did not measure how many people might develop cancer from vaping, but instead assessed whether it causes the kinds of biological changes known to lead to the disease.”
INSUFFICIENT EVIDENCE
No evidence found in web search, cross-references, or Wikipedia to support the review's scope claim.
Claim 14: “There is no doubt that the cells and tissues of the oral cavity, the mouth and the lungs are altered by inhalation from e-cigarettes, Stewart said.”
INSUFFICIENT EVIDENCE
No evidence found in web search, cross-references, or Wikipedia to support the cellular alteration claim.
Claim 15: “Modern e-cigarettes were only invented in the early 2000s, there is not enough long-term data from large numbers of people vaping and who developed cancer to determine definitive risk.”
