Before you trash your cellphones (or rather, responsibly recycle and dispose of them), a careful review of the data—and the real life human implications—is needed. Here are the facts:
The National Toxicology Program (NTP) just concluded a massive 2-year study investigating the potential health hazards of cellphone use on rats and mice – most notably including the specific radio frequencies and modulations (RF-EMF) currently used in our U.S. telecommunications industry.
The NTP have chosen to publish their preliminary findings in rats, rather than wait. This study found that cellphone exposure increases the incidence of malignant gliomas of the brain, i.e., brain cancer, and schwannomas (also called neuromas) of the heart in the male rats. While schwannomas are not cancers, they are tumors and can profoundly impact the protective sheathing of the peripheral nerves, which can lead to severe pain and disability.
The increases were small (3-4 percent over controls), but since these are rare tumors, the findings are still significant. What make these studies even more significant are the findings of similar tumors in humans.
