Researchers in Japan have ruled out any link between mobile phone use and an increased risk of brain tumours.
Their study, which was published in the British Journal of Cancer, is the first to look at the effects of hand set radiation levels on different parts of the brain.
And the scientists concluded that regular mobile phone users experienced no increased risk of the three main types of brain cancer.
A team led by Professor Naohito Yamaguchi, from Tokyo Women's Medical University, compared 322 brain cancer patients and 683 healthy people in Tokyo, looking at their history of mobile phone use.
Levels of electromagnetic radiation exposure were assessed in terms of the number of years since a mobile was first used, the average daily number of hours spent talking on a mobile phone, and which parts of the brain were most likely to be affected.
Prof Yamaguchi said: "We studied the radiation emitted from various types of mobile phones and placed them into one of four categories relating to radiation strength. We then analysed how they would affect different areas of the brain areas, taking into account the organ's complex structure.
"We found no association between mobile phone use and cancer, providing more evidence to suggest they don't cause brain cancer."
