A landmark study into the health dangers posed by mobiles has found people who speak on their handset for more than half an hour a day over 10 years are at greater risk of brain cancer.
The World Health Organisation's Interphone report, to be published this week, will say that "heavy users" are more at risk of developing glioma tumours.
It concludes that there is no increased risk of developing the disease in other users.
However, the minimum amount of time which researchers designated at heavy use was just 30 minutes a day.
