“But critics warn the study only identifies a trend in tumor diagnosis rates and does not provide sufficient evidence that mobiles are to blame.
Keith Neal, from the University of Nottingham, said: “The suggestion that mobile phone use is responsible cannot be substantiated. The rise is greatest in the over 55s, who use mobile phones much less and there was very little mobile phone use in 1995 when rates are already increasing.””
That bit about diagnosis rates is a key point.
Medical imaging techniques, particularly involving the brain, are infinitely better than they were twenty years ago.
