Institute warns faculty, staff about possible cell phone health risks

The head of a prominent cancer research institute issued an unprecedented warning to his faculty and staff Wednesday: Limit cell phone use because of the possible risk of cancer. The warning from Dr. Ronald B. Herberman, director of the University of Pittsburgh Cancer Institute, is contrary to numerous studies that don't find a link between increased tumors and cell phone use, and a public lack of worry by the US Food and Drug Administration. Herberman's advice is sure to raise concern among many cell phone users and especially parents. In the memo he sent to about 3,000 faculty and staff Wednesday, he says children should use cell phones only for emergencies because their brains are still developing.
