Interphone study reveiwed 5,100 people diagnosed with brain cancers in 13 countries, including Canada
The most exhaustive investigation ever undertaken into brain cancer risk from cell phones suggests that heavy users may be at an elevated risk of developing the tumors, a finding that is likely to continue fueling health concerns over the popular electronic gadgets.
The study, dubbed Interphone, found that that people who reported chatting on the phones the equivalent of a half an hour a day over 10 years had an elevated risk of a rare and often deadly brain cancer known as glioma, the type that last year felled U.S. Senator Ted Kennedy, although the researchers concluded their evidence is not strong enough to link the devices to the disease.
The frequent users had a 40 per cent higher risk of glioma, compared to people who never used the phones, as well as about twice the risk of developing tumors on the same side of their heads where they normally held their mobiles while talking, or where most of the energy emitted by their phones would be absorbed.
The results were based on
