E-cigarettes (vaping) are often thought to be less harmful than traditional cigarettes, but research emerging in recent years is raising questions about this notion. Scientists say that the smoke that enters the body during vaping is full of many chemicals, which can increase the risk of serious diseases, especially cancer, in the long run. Although it has not yet been directly proven that e-cigarettes cause cancer, the available scientific evidence is enough to raise concerns.
What came out in the research?
Scientists studied the health effects of vaping in an analysis of peer-reviewed research published between 2017 and 2025. These studies found that the smoke emitted from e-cigarettes contains nicotine, its by-products and microscopic particles of metals. These are chemicals which have many carcinogenic properties. Researchers say that the effect of these elements is not limited to the lungs only, but can affect the entire body.
Blood and urine tests raise concerns
Studies conducted using blood and urine tests confirmed that people vaping were absorbing chemicals associated with e-cigarettes. These are the same chemicals that are known to be linked to cancer. This indicates that during vaping the body comes in direct contact with such elements, which can be harmful to health in the long run.
Changes seen in DNA and cells
The research also found that changes were seen in the DNA of the mouth and lung cells of those who vaped. Additionally, changes in cancer-associated biomarkers were also recorded. Biomarkers are biological signals that indicate changes in cells before tumor formation. According to experts, these findings may indicate a possible risk of cancer in the future.
No conclusive conclusion yet, but danger signs clear
Scientists say it took almost 100 years for the link between smoking and lung cancer to be established. Similarly, the long-term effects of vaping may take decades to understand. At present, it is too early to say how many people will get cancer from e-cigarettes, but it would not be appropriate to assume that vaping is completely safe or that its risk is very low.
Both awareness and research are important
Experts believe that long-term scientific studies need to be conducted only on people who vape, so that its actual health effects can be clearly assessed. Also, it is important for people to understand that e-cigarettes cannot be considered a safe alternative to smoking. By timely awareness, scientific research and adopting effective health policies, the risk of serious diseases like cancer can be reduced in future.
