This effect would be cumulative with certain molecules, which means that the cumulative effect of speaking on cell phones over many years may pose a danger.

Other peer reviewed studies have been held and usually say that there is no risk, but still suggest not to allow children to use cell phones (which one must admit is somewhat suspicious). Considering how long it took for conclusive proof about smoking to be uncovered as dangerous, I would like to see a lot more study.
