Model 900, 1800 MHz (GSM) exposure due to mobile phone use and correlation with brain tumors

Patients (n=73) with unilateral glioma were assessed for mobile phone history to test the idea that if a mobile phone were to cause a glioma then it would do so on the dominant-hand side. While as expected, most patients (69 of 73) were right-handed and most tumors (48 of 73) occurred on the right side, the authors found no statistical evidence revealing any association between right handed users and tumors on the right side of the brain. The authors further noted that data from the Irish National Cancer Registry from 1994 to 1997 shows no increasing brain tumor trend with increased mobile phone use in the same period. Further, the results were the same (from an anatomical location perspective) with a similar study performed 10 years earlier by the same group, suggesting no influence of growing mobile phone technology on relocating the predominant sites of tumor localization.

    Dose assessment was performed using a very general inquiry regarding handedness (which may not apply to situations like driving, etc), the type of mobile phone used (which may have changed many times during the years), duration in years and estimated daily hours of use, along with antenna specifications. The protocol makes it clear many of the patients were "confused" and so a proxy for the questionnaire / interview information was required, making the dose assessment even more likely to contain recall error.
