Forty-four years ago, cigarettes were labeled as having the potential to cause cancer. Should cell phones include similar warnings about brain cancer? Or is there no credible medical evidence suggesting a link between cancer and cell phones? Given the prevalence of cell phones, should wireless companies be required to fund an independent study to

determine where there are health threats from using the phones?
