TUESDAY, Dec. 5, 2006 (HealthDay News) -- Fears that cell phones might cause cancer appear to be all talk, researchers report.
A major new Danish study finds no link between short- or long-term use of the devices and risks for malignancy.
Cell phones antennas emit electromagnetic fields that can penetrate into the human brain and concerns have been raised that this may increase the risk of tumors in the head or neck.
In their study in the Dec. 6 issue of the Journal of the National Cancer Institute, researchers at the Danish Institute of Cancer Epidemiology in Copenhagen studied 420,095 people who first started using cell phones between 1982 and 1995. They then tracked their health through 2002.
The study found no association between short- or long-term cell phone use and brain tumors, salivary gland tumors, eye tumors or leukemias.
The findings "suggest that the use of cellular telephones does not pose a substantial risk of brain tumors among short-term or long-term users," the study authors wrote.
