Can cell phone use cause damage to the brain?

Urban myth: Many studies have been done on this point and no damage has ever been proven. The only damage known is due to the things that people constantly say to each other over their cellular phones.

U.S. C.D.C. says...: In the last 15 years, hundreds of research studies have investigated whether health problems can be linked to cell phone use. Some of these studies have suggested the possibility that long-term, high cell phone use may be linked to certain types of brain cancer. These studies do not establish this link definitively. Scientists will need to conduct more studies to learn more about possible risks.
