Use of wireless phones and the risk of meningioma

No consistent association between use of mobile phones and cordless phones and risk meningioma has been shown in previous studies by our research group in Sweden and the Interphone study at IARC (WHO).

We have now performed a new case-control study including patients with meningioma diagnosed between 2007-2009. Again this study did not show a consistent increased risk of meningioma for use of mobile and cordless phones. The latency time (time from first use of the phone until tumour diagnosis) was in this new study longer than previously, at most > 25 years.

Thus, in the same studies different risks have been found for different tumour types; increased risk for malignant brain tumours (mostly glioma) and acoustic neuroma but not for meningioma. These results clearly indicate that the results cannot be explained by systematic bias in the studies. The conclusion is that wireless phones cause malignant brain tumours and acoustic neuroma.
