Does using cell phone cause cancer?

Cell phones emit radiofrequency energy (radio waves), a form of non-ionizing radiation. There are concerns that this form of radiation when placed close to the head may affect the brain and other tissues. However, there isn’t enough strong evidence at this time to show that it causes damage in cells or increases cancer risks.
If you are concerned about exposure to radiofrequency energy from cell phones, use an ear piece and limit your time on the phone.
