Mobile phones cause cancer...or notOne result of
'borderline statistical significance'

People using a mobile phone for more than 10 years have a 40 per
cent increased chance of developing glioma (a kind of brain
tumour), according to research reported in the Telegraph.
However, the study referenced would seem less clear-cut, and
certainly the authors draw less compelling conclusions.
The study involved questioning 4,822 people, of whom 1,521 were
glioma patients. The idea was to establish which hand the patients
used to hold a phone, and thus which side of the head the phone was
near. This data is then compared with the side of the head on which
the glioma appeared.
Overall, the study found no evidence of mobile phone use
influencing the incidence of glimoa, but if only those who had used
a phone for more than 10 years are included (all 222 of them),
there is a match at a level the report's authors describe as "of
borderline statistical significance".
This could be down to the inaccurate memories of the subjects,
statistical coincidence or, possibly, phones effecting glimoa. The
report calls for more research.
