              Abstract: 
              The widespread use of cellular telephones has generated concern 
              about possible adverse health effects, particularly brain tumors. 
              In this population-based case-control study carried out in three 
              regions of Germany, all incident cases of glioma and meningioma 
              among patients aged 30-69 years were ascertained during 2000-2003. 
              Controls matched on age, gender, and region were randomly drawn 
              from population registries. In total, 366 glioma cases, 381 
              meningioma cases, and 1,494 controls were interviewed. Overall use 
              of a cellular phone was not associated with brain tumor risk; the 
              respective odds ratios were 0.98 (95% confidence interval (CI): 
              0.74, 1.29) for glioma and 0.84 (95% CI: 0.62, 1.13) for 
              meningioma. Among persons who had used cellular phones for 10 or 
              more years, increased risk was found for glioma (odds ratio=2.20, 
              95% CI: 0.94, 5.11) but not for meningioma (odds ratio=1.09, 95% 
              CI: 0.35, 3.37). No excess of temporal glioma (p=0.41) or 
              meningioma (p=0.43) was observed in cellular phone users as 
              compared with nonusers. Cordless phone use was not related to 
              either glioma risk or meningioma risk. In conclusion, no overall 
              increased risk of glioma or meningioma was observed among these 
              cellular phone users; however, for long-term cellular phone users, 
              results need to be confirmed before firm conclusions can be drawn.
