Many people claim that cell phones are unsafe and that the damage they cause has yet to be revealed, but the benefits they provide far outweigh any potential and unproven risks. Which best addresses a potential counterclaim? Certain types of cancers take twenty to thirty years to develop, and cell phone studies have only been monitoring this potential connection for ten years or less.
