Radio frequency energy emitted by phones can be the reason for increased cancer risk. It could also be blamed tumour in acoustic nerves and the salivary glands, Express.co.uk reports.

Researchers, however, have not revealed any definite ill-effects of using mobile phones but people who wish to cut down their risk of developing brain cancer in any way should keep their phones away from their head before going off to sleep.

The Department of Health said, “When a phone sends signals to a tower, the radio frequency energy goes from the phone’s antenna out in all directions, including into the head and body of the person using the phone. Cell phones work by sending and receiving signals to and from cell phone towers. Don’t sleep with your phone in your bed or near your head.”
