Cell phone radiation linked to brain cancer - study confirms
By David Liu, PHD
Friday Dec 30, 2011 (foodconsumer.org) -- The debate on the association between cell phone radiation and brain cancer has not been dead yet. E. Cardis of Hospital del Mar Research Institute and colleagues in Barcelona, Spain have recently confirmed that over-exposure to Cell phone radio frequency fields boosts risk for both glioma and meningioma.
Glioma is a tumor that arises from glioma cells and meningioma is originated from the meninges.
The Interphone Study released in the Sept 2011 issue of Occupational and Environmental Medicine found the following:
Men and women who ever regularly used cell phones or mobile phones were 7 percent more likely to be diagnosed with glioma and 20 percent more likely to develop meningioma.
Men and women who were in the highest quintile of total cumulative specific energy from cell phones were 35 percent more likely to develop glioma.
Men and women who were in the highest quintile of total cumulative specific energy from cell phones seven plus years before diagnosis were 91 percent more likely to be diagnosed with glioma brain tumors.
The researchers compared brain tumors in the most exposed area of the brain with glioma and meningiomas located in other parts of the brain and found that among those who had used cell phones for more than 10 years, these tumors were 180 percent more likely to be found in the most exposed areas.
Similar associations were found for meningioma, even though the magnitude of increased risk for meningiomas was not as great as that for glioma.
The findings were based on analyses of data from 553 cases of glioma and 676 cases of meningioma, and 1762 and 1911 controls, respectively. The patients with brain tumour were enrolled in the Australian, Canadian, French, Israeli and New Zealand components of the Interphone Study.
The findings are significant as the Interphone Study was directly or indirectly sponsored by the telecommunication industry and other early reports from the study did not reveal significant associations between cell phone use and elevated risk for brain cancer.
