A new study from the UK's Health Protection Agency, the largest of its kind, debunks the association between cellphone use and brain tumors. (Note that some scientists warn that any long-term health effects may not yet be visible.) The latest conclusions came from interviews with 966 people with tumors and 1716 "apparently healthy" individuals. From New Scientist:
The study did find an association between the location of a tumour and side of the head that patients said they most often used to make calls. But when the team considered handedness – which correlates to the side of the head to which cellphones are most commonly held – there was no link.
In light of the overall study results the researchers believe the association was an anomaly – they suggest these patients most probably misremembered their cellphone usage, in an effort to explain the tumour.
