The truth about the dangers of cigarette smoking was suppressed for many years due to the influence (monetary and political) of the tobacco companies. Meanwhile, millions died from lung cancer and COPD and continue to do so. Given the tremendous economic impact of the cell phone market world wide, it is easy to envision that studies showing an association between cell phone usage and cancer would likewise be suppressed. Back in the day, most 12 year olds were not chain smokers. In contrast, I know kids as young as 9 or 10 that have cell phones and use them constantly. There is no disputing that cell phones give off radiation. It may take awhile to ascertain the health risks associated with long term use of cell phones. Meanwhile, it makes sense to err on the side of safety and try to limit excessive cell phone use. This is easier said then done.
