TAILIEUCHUNG - Interphone study reports on mobile phone use and brain cancer risk

Researchers in the field agree that in general the diagnosis of cancer elicits greater dis- tress than any other disease. The literature documents numerous negative psychological consequences for patients including depression (Meyerowitz, 1980), anxiety (Ervin, 1973), and hostility and anger (Vachon & Lyall, 1976). Earlier observational reports (Bard, 1955; Bard & Sutherland, 1952; Renneker & Cutler, 1952) were confirmed by cross- sectional studies finding high levels of depression, sadness, anger, frustration, panic and anxiety, and suicidal ideation (Grandstaff, 1976; Jamison, Wellisch, & Pasnau, 1978) | International Agency for Research on Cancer ếổm World Health Organization PRESS RELEASE N 200 17 MAY 2010 Interphone study reports on mobile phone use and brain cancer risk The Interphone Study Group today published their results1 in the International Journal of Epidemiology direct media link . 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 casecontrol studies including several of the national components of Interphone. No studies however have included as many exposed cases particularly long-term and heavy users of mobile phones as this study. Background Mobile phone use has increased dramatically since its introduction in the early-to-mid 1980 s. The expanding use of this technology has been accompanied by concerns about health. In the late 1990s several expert groups critically reviewed the evidence on health effects of low-level exposure to radiofrequency RF electromagnetic fields and recommended research into the possible adverse health effects of mobile telephone use. IARC co-ordination of a multinational effort in cancer research As a result the International Agency for Research on Cancer IARC coordinated a feasibility study in 1998 and 1999 which concluded that an international study of the relationship between mobile phone use and brain tumour risk would be feasible and informative. Scope of the Interphone study Interphone was therefore initiated in 2000 as an international set of case-control studies in 13 countries around the world2 focusing on four types of tumours in tissues that most absorb RF energy emitted by mobile phones tumours of the brain glioma3 and meningioma4 of .
