Interphone study on mobile phone use and brain cancer risk

Do mobile phones pose a cancer risk? Coordinated by WHO’s International Agency for Research on Cancer (IARC), the largest ever international study of mobile phone safety has concluded that the devices do not raise the risk of brain cancer, except for a possible slight increase in tumours among the most intensive users. The Interphone Study Group published their results in the International Journal of Epidemiology. The paper presents the results of analyses of brain tumour (glioma and meningioma) risk in relation to mobile phone use in all Interphone study centres combined. This interview-based case-control study, which included 2708 glioma and 2409 meningioma cases, and matched controls, was conducted in 13 countries using a common protocol. Analyses of brain tumours in relation to mobile phone use have been reported from a number of cohort and case-control studies, including several of the national components of Interphone. No studies, however, have included as many exposed cases as this study, particularly long-term and heavy users of mobile phones.
