Further research has been published suggesting there is no link between mobile phones and brain cancer. The risk mobiles present has been much debated over the past 20 years as use of the phones has soared. The latest study led by the Institute of Cancer Epidemiology in Denmark looked at more than 350,000 people with mobile phones over an 18-year period. Researchers concluded users were at no greater risk than anyone else of developing brain cancer. The findings, published on the British Medical Journal website, come after a series of studies have come to similar conclusions.
