Research published online in the British Medical Journal suggests, there is no link between the long-term use of a mobile phone and brain cancer. Researchers at the Institute of Cancer Epidemiology in Copenhagen, Denmark looked at 358,000 people over a period of 18 years and found cancer rates were almost the same in both long-term mobile phone users and people who do not use the handsets.
The study concluded that mobile phone use does not increase the risk of developing tumours of the brain or nervous system or, indeed, any cancer.
“There was no indication of dose-response relation either by years since first subscription for a mobile phone or by anatomical location of the tumor; that is, in regions of the brain closest to where the handset is usually held to the head,” the study concluded.
“The extended follow-up allowed us to investigate effects in people who had used mobile phones for 10 years or more and this long-term use was not associated with higher cancer risks.” Although they added, “A small to moderate increase in risk for sub-groups of heavy users or after even longer induction periods than 10-15 years cannot be ruled out.”
Earlier this year, the World Health Organisation warned that mobile phones may cause cancer and urged owners to limit their use. The WHO’s Interphone Study Group said that using a mobile for 15 minutes a day could substantially increase the risk of brain cancer and the longer people used them the higher the risk.
