Karolinksa Group Finds No Brain Tumor Risk from Mobile Phones
December 17, 2004
Epidemiologists at the Karolinska Institute in Stockholm have found no association between the use of cell phones and the risk of brain tumors.
“No increased risk was found for glioma or meningioma related to mobile phone use,” reports Stefan Lönn and coworkers at the Institute of Environmental Medicine. Lönn completed the study as part of his doctoral dissertation under the direction of Maria Feychting. This work is part of the Interphone study being coordinated by the International Agency for Research on Cancer (IARC) in Lyon, France.
Lönn defended his dissertation on December 17 and a summary of his results are posted on the Karolinska Web site. They have not yet been published in a journal.
In October, Lönn, Feychting and Anders Ahlbom announced that they had found an increased risk of acoustic neuroma among those who had used cell phones for more than ten years.
“The number of long-term exposed cases of meningioma is about the same as for acoustic neuroma,” Feychting told Microwave News. “And the number of glioma cases is much higher.”
“As for acoustic neuroma,” Feychting added, “We have to await the results from the other Interphone studies before we can draw any firmer conclusions.”
