WASHINGTON (AP) – Two government studies that bombarded rats and mice with cellphone radiation found a weak link to some heart tumors, but federal regulators and some scientists say don’t worry – it is safe to use your device. They still do.
Previous studies of cellphone users had found little reason for concern, but the newest research took a closer look at the effects of super-high doses in animals to address some lingering questions that could not be tested on humans.
The rat study released Friday found a small increase in an unusual type of heart tumor in male rats, but there were no significant problems in female rats or in a separate study of mice. In particular, scientists could not find hard evidence for concern about brain tumors.
