FRIDAY, Jan. 20 (HealthDay News) -- There is no evidence that mobile phone use raises the risk of glioma, according to a study published online Jan. 20 in BMJ.
Sarah J. Hepworth, of the University of Leeds, U.K., and colleagues interviewed 996 people diagnosed with glioma, as well as 1,716 randomly selected, healthy controls about their mobile phone use habits, including history of mobile phone, hours of use, duration of calls, and make and model of phones that they had used.
There was no association between the risk of glioma and the time since first use of a mobile phone, total years of use, hours of use and cumulative number or calls. There was a greater risk associated with mobile phone use on the same side as the tumor and a lower risk for phone use contralateral to the tumor, but this was attributed to probable recall bias. As mobile phones have only been in widespread use for about a decade in the United Kingdom, the study was not able to assess long-term risk.
"There is generally a lack of convincing and consistent evidence of any effect of exposure to radiofrequency field on risk of cancer. Overall, our findings are consistent with this and with most studies on mobile phone use," the authors conclude.
