Mobile phones are not associated with an increased risk of the most common type of brain tumour, finds the first UK study of the relationship between mobile phone use and risk of glioma. The results are published online by the British Medical Journal. The four year study by the Universities of Leeds, Nottingham and Manchester and the Institute of Cancer Research, London found those who had regularly used a mobile phone were not at a greater overall risk of developing this type of tumour.
A significantly increased risk was found for tumours which developed on the same side of the head as the phone was reported to have been held but this was mirrored by a decrease in the risk on the opposite side of the head making it difficult to interpret as a real effect.
