Pituitary tumor risk in relation to mobile phone use: A case-control study

Authored By:

This is a case-control study which looked into the association between pituitary tumour and mobile phone use, which was conducted as part of the Interphone study. A total of 80 cases and 240 controls were recruited in the study and were compared for their mobile phone use. The study found a reduced risk of pituitary tumour with regular mobile phone use (odds ratio, OR = 0.39, 95% confidence interval, 95% CI = 0.21 – 0.72), and mobile phone use of 10 years or more (OR = 0.69, 95% CI = 0.25 – 1.89). The authors conclude that there was no increased risk of pituitary tumour related to mobile phone use. They note that the reduced risks may be related to selection bias among the controls (i.e. greater participation of controls that have higher mobile phone use).
