Do They or Don't They?

So do cell phones cause brain cancer, or don't they? Only a few weeks after the World Health Organization's International Agency for Research on Cancer placed cell phones on a list with pickles and coffee as possible carcinogens, a study published in the American Journal of Epidemiology by an IARC researcher seems to show that cells phones don't increase the risk of a noncancerous brain tumor, says the Huffington Post's Amanda Chan. Even though acoustic neuromas aren't cancerous, they can still help researchers determine whether cells phones could cause cancer, Chan adds. The study, for which researchers followed nearly 3 million Danish adults, showed that people who use a cell phone for more than 11 years are not more likely to develop a noncancerous brain tumor, like an acoustic neuroma, than those who don't use a cell phone, Chan says. The study's authors do say that no one has been using a cell phone long enough to definitively rule out a link to brain cancer, but most studies so far have not shown any link between the two.
