This field of research is so muddled (due in no small part to deliberate FUD on both sides) that it will probably take decades to satisfactorily sort it all out. But studies like this one are good, at least until the press gets ahold of them. It provides solid evidence that mobile phone use does not increase the risk of glioma. It says nothing about the other types of cancer that phones have been implicated as causing, some of which develop in the brain and some in the ear, which will all have to be studied individually. And then there is still the matter of analog transmission, tested by many previous (and some current) surveys, whose effects are largely unrelated to those of the much more common digital methods! Anyone waiting for complete results will never be able to get a mobile. The rest of us should just keep to an absolute minimum their use right against our heads, laugh at the conflicting results (so we don't cry :roll
, and perhaps maintain a scoreboard like
Engadget's.
