New evidence always seems to emerge to support or refute such a link. On Wednesday, another study was added to the list. A European study involving nearly 1,000 participants found no link between cell phone use and brain tumors in children and adolescents. This marks the 3rd study this month and the 4th major one this year, all with different conclusions."
