An international panel of experts says cellphones are possibly carcinogenic to humans after reviewing details from dozens of published studies on the matter.
The statement was issued in Lyon, France, Tuesday by the International Agency for Research on Cancer - the cancer agency of the World Health Organization. The assessment by the cancer panel now goes to WHO and national health agencies for possible guidance on cellphone use.
Last year, results of a large study found no clear link between cellphones and cancer.
But some advocacy groups contend the study raised serious concerns because it showed a hint of a possible link between very heavy phone use and a rare but often deadly form of brain tumor. However, the numbers in that subgroup weren't sufficient to make the case.
