WASHINGTON-A newly published Danish study found no link between cell-phone use and risk for certain brain tumors. The study, part of a large multi-nation European study, was published Tuesday by the American Academy of Neurology in the journal Neurology.
The population-based, incident case-control epidemiology study focused on the relationship between mobile-phone use and cases of glioma and meningioma.
The authors ascertained all incident cases of glioma and meningioma diagnosed in Denmark between Sept. 1, 2000, and Aug. 31, 2002. They enrolled 252 persons with glioma and 175 persons with meningioma aged 20 to 69. The authors also enrolled 822 randomly sampled, population-based controls matched for age and sex. Information was obtained from personal interviews, medical records containing diagnoses, and the results of radiologic examinations. For a small number of cases and controls, the authors obtained the numbers of incoming and outgoing wireless calls. They evaluated the memory of the respondents with the Mini-Mental State Examination and obtained data on socioeconomic factors from Statistics Denmark.
The findings come as six brain-cancer lawsuits and four health-related class-actions suits have been returned to state courts around the country for further proceedings.
