A case-control study was conducted in Greece to investigate potential predisposing factors of cerebral gliomas. Mobile phone use was one of the studied factors besides alcohol, tobacco, and severe head trauma.
Mobile phone use was estimated by multiplying the minutes spent talking per day by the number of years of use.
The age-adjusted incidence rate of glioma in Northwest Greece was 5.6 cases per 10,000 inhabitants which is higher compared with data of European, Asian and US populations.
No significant association between mobile phone use and the risk for glioma was observed (OR 1.00, 0.99-1.01).
