Are mobile phones bad for your health? A Swedish study has shown an increased risk of an uncommon form of brain tumour in people who used mobiles for longer than ten years.
It's an important question given that worldwide, about 1.5 billion people use one. This year 650 million are expected to be sold. If they are harmful, the health of very large populations could be at risk.
We do know that mobile phones emit radiofrequency radiation from the handset and that these low-energy electromagnetic waves travel into the head. But do they cause injury to living tissue, possibly triggering a brain tumour or other disease?..
