Mobile phones 'linked to brain cancer'
A $30 million international study into mobile phones has found a link between long-term use and brain tumours.
Britain's Daily Telegraph reports the World Health Organisation (WHO) will publish evidence showing prolonged use of a mobile phone increases the risk of developing brain tumours later in life.

Head of the WHO Interphone study, Dr Elisabeth Cardis, said the report would include a public health message and recommend children limit their use of mobiles.
"I would not go as far as banning mobile phones as they can be a very important tool, not only in emergencies, but also maintaining contact between children and their parents and thus playing a reassurance role," she said.
"In the absence of definitive results and in the light of a number of studies which, though limited, suggest a possible effect of radio frequency radiation, precautions are important."
The decade-long investigation may counteract previous studies and the assurances of mobile phone companies that their products are safe.
A leading researcher says the study has not found anything conclusive.
Professor Bruce Armstrong from the University of Sydney is working on the WHO study.
He says the study has not yet confirmed whether or not there is an increased risk of cancer from mobile phone use.
He expects the findings of the study to be released by the end of the year.
"There is, as far as a I know, absolutely no information circulating at the moment that is accurate and correct with respects to the results of that study," he said.
"I'm expecting that there will be no such information until it is actually published."
