Swedish study of long-term mobile phone users found no increased brain tumor risk after more than 10 years of use.

Plain English Summary

Summary written for general audiences

Swedish researchers studied whether long-term mobile phone use increases brain tumor risk by comparing 644 brain tumor patients with 674 healthy controls over a period when many people had used phones for more than 10 years. They found no increased risk of glioma or meningioma brain tumors, even among the heaviest users. The study actually showed slightly lower tumor rates among phone users, though this protective effect was likely due to study limitations rather than phones preventing cancer.

Study Details

The purpose of this population-based, case-control study was to test the hypothesis that long-term mobile phone use increases the risk of brain tumors.

The authors identified all cases aged 20-69 years who were diagnosed with glioma or meningioma durin...

For regular mobile phone use, the odds ratio was 0.8 (95% confidence interval: 0.6, 1.0) for glioma ...

This study includes a large number of long-term mobile phone users, and the authors conclude that the data do not support the hypothesis that mobile phone use is related to an increased risk of glioma or meningioma.
