better to be safe than sorry, as they say.
one thing wrong with the study's methodology, as reported, was that there was an increase in the widespread use of cellphones while the study was being undertaken. it also included the analog cell phones common in the 1990s as against the current digital ones that are more common now, which have less radiations. these changed the definitions of the study.
also, the latency period of glioma, a type of brain cancer, is 25 years, a period longer than the current widespread use of cellphones.
what is advised though is the use of hands-free phones instead because what is worrisome is the fact that scientists cannot categorically conclude either way--- that cell phone use may or may not cause brain cancer.
(note: i read these additional details from yahoo! news with great interest because just now i am trying to come up with good reasons on why our 8-year-old girl shouldn't have a cell phone.)
