WHO study: Dangers from cell phones?

A World Health Organization panel is reporting that cellphones are “possibly carcinogenic,’’ a significant development in that the group has previously said there were no negative health effects.

Last night on ABC News, Dr. Richard Besser broke down the study in a brief exchange with news anchor Diane Sawyer.

Although the information on cell phones is still spotty, international studies report deleterious effects from cell phone towers.
