This was a case control study conducted across four areas of France between 2004 and 2006, which looked at the association between mobile phone use in adults, and “primary tumors” of the brain or spinal cord.
The study was carried out by researchers from Université Bordeaux Segalen in France, and was supported by grants from various French health and research organizations. The study was published in the peer-reviewed journal of Occupational and Environmental Medicine.
“In our study, we found an increased risk in those subjects reporting a prolonged use, making numerous calls, whose use was especially occupational and more often in urban areas…” For ≥ 986 h of life-long use, OR=2.89, 95% CI: 1.41-5.93 for gliomas; OR=2.57, 95% CI: 1.02-6.44 for meningiomas; for ≥18,360 calls, OR=2.10, 95% CI: 1.03-4.31 for gliomas. (All these elevated risks are statistically significant.)
Conclusion: These additional data support previous findings concerning a possible association between heavy mobile phone use and brain tumors.
