Have you heard that cell phones cause cancer, then they don’t, then they do? Confused enough yet? Let me break it down for you. Contrary to some claims, the new US government study by the National Toxicology Program (NTP) is hardly a shot in the dark or a one-off event. With this largest best-conducted animal study, we now have three different studies within the past six years where animals develop some of the same cancers from cell phone radiation as people. In the NTP study, male rats exposed to wireless radiation develop more unusual highly malignant brain tumors—gliomas—as well as very rare tumors of the nerves around and within the heart—schwannomas.
