Since cell phones were invented in the 1980's, there has been a constant speculation of cancer risks. Many scientific reports have been published; I won't dwell into that. Today there are 3 billion users of cell phones. Statistically the number of user-hours is astronomical while the number of possible links to cancer is hardly worth a mention. I am not down playing the possibility that cell phones may in some cases contribute to cancer. I just want to point out that this is an unnecessary concern at this time.
Consider this: airplanes have been around for a long time. Everyone knows air disasters do happen and will continue to happen. Yet almost everyone will continue to fly in an airplane. The reason is, the advantage far outweighs the risk. Back to the cell phone... even if a direct correlation to cancer is found, people will continue to use cell phones unless the risk is unacceptably high. Of far greater danger to health and safety are cigarettes, airplanes, or even simply crossing the road. Aren't we missing something here?
