E-cigarettes are still fairly new, and more research is needed over a longer period of time to know what the long-term effects may be. The reaction of carcinogens with DNA can cause mutations and, if unrepaired, can lead to the activation of oncogenes or the inactivation of tumor suppressors.

How your body reacts to this level of exposure, the length, the time, and the intensity of the exposure, combined with your genetic makeup, will determine the risk of developing cancer.
