Over the past decade, there have been a couple of dozen studies looking at the health risk of mobile phones, in particular the risk of brain tumours.
The vast majority have failed to establish an increased cancer risk, but one Swedish study did find a statistical association, which fell far short of linking cause and effect.
Brain tumours are very rare and even if mobile phones increased the risk significantly, the total number would increase by only a few cases nationally.
