Mixed signal from mobile studies review
Studies on whether mobile phones can cause cancer vary widely in quality and there may be some bias in those showing the least risk, a review has found.
The best studies suggest some association between mobile phone use and cancer, the team led by Dr Seung-Kwon Myung of South Korea's National Cancer Centre found.
Dr Myung and colleagues at Ewha Womans University and Seoul National University Hospital in Seoul and the University of California, Berkeley, examined 23 published studies of more than 37,000 people in what is called a meta-analysis.
