Cell phones are still too new to find the facts for many decades of use and there's been little search in children is developing brains may make them more susceptible to any risks from phones. What we do know is that brain tumor rates have so far not gone up as cell phone use has increase. And lab study showed the type of radiation from cell phones so called non-ionizing radiation does not damage DNA or cause cancer in animals.
