Long-term mobile phone use could increase the risk of developing cancer, according to a decade-long landmark study.
The investigation by the World Health Organisation analysed studies of 12,800 people in 13 countries.
It found people who used mobiles for a decade or more had a 'significantly increased risk' of developing some types of brain tumours.
Six of the eight Interphone studies found an increased risk of glioma - the most common brain tumour - among mobile phone users, according to The Daily Telegraph.
The head of the WHO study, Dr Elisabeth Cardis, said the report would recommend young children should have restricted access to mobile phones.
She said it will also include a 'public health message.'
Dr Cardis added that although the study was not definitive, precautions were important.
Some critics said the report may have underplayed the results because it did not study any children.
They pointed out that the Interphone investigation was also partly funded by the mobile phone industry.

- Send texts rather than call on your mobile
- Use a hands free kit when making calls
- Avoid using your phone if the signal is weak
However, others claimed the results may be flawed as some of the studies seemed to suggest short-term use could protect the brain from cancer.
Plus a summary of studies on acoustic neurinoma (a benign tumour of a nerve between the ear and brain) said the condition could not be definitively linked with mobiles because of difficulties with subjects’ memories.
Publication of the results of the £20million investigation have been delayed over disagreements how best to present the conclusions.
However they have been submitted to a scientific journal and should be published within the next few months.
