Are Cell Phones Dangerous? Recent research indicates that microwaves from mobile phones can affect parts of your brain – after all you are holding a transmitter to your head. Other research is inconclusive, although there is a feeling among scientists that you are more vulnerable of brain damage from cell phone use when you are young and your brain is still growing. Go to watch the Larry King Live Video then add your opinion to the discussion
