Cell phone radiation could pose a risk of certain cancers to some, the preliminary findings of two new major studies from the National Institutes Health suggest.
Six percent of male rats exposed to the same kind of radiation our cell phones emit - though in much larger quantities - developed a type of cancer called a schwannoma in their hearts.
The pair of studies are the largest the National Toxicology Program has ever conducted about the carcinogenic effects of cell phone radiation.
The authors caution that while much more research is needed to find out whether or not the ways that average people use cell phones could raise cancer risks, the findings highlight an 'area of concern'.
Over the course of the last two years, researchers at the National Toxicology Program (NTP) of the National Institutes of Health (NIH) have been exposing rats and mice to varying levels of cell phone radio frequency radiation.
