A total of 792 glioma cases who were regular mobile phone users (who made at least 1 call a week for a period of 6 months or more) and had preference on which side of the head they used a mobile phone (right ear or left ear) were included in the analyses. The distance from the preferred ear to the tumour location in the head was analysed. The authors suggested that using a mobile phone regularly is associated with glioma localisation that is closer to the preferred side of the head when a mobile phone is used. However no association was found on the cumulative call time and cumulative number of calls.

Am J Epidemiol 2016This study by Grell et al aimed to investigate the association between the localised absorption of radiofrequency (RF) electromagnetic energy (EME) in the human brain as a result of using a mobile phone and the location of the brain tumour. Grell et al suggested an association with location of glioma closer to the preferred side of the head when a mobile phone is used, however the absence of an association with increasing call duration and increasing number of calls may imply that recall bias affected the findings. The information on the preferred side of head while using a mobile phone was self-reported.
A study conducted by Larjavaara et al (reported in May 2011’s report) which also studied the association between glioma location and mobile phone use did not suggest that gliomas in mobile phone users are preferentially located in the parts of the brain with the highest RF exposure from mobile phones.
