We published recently a pooled analysis of our case-control studies on glioma and use of mobile phones and cordless phones. The study has been published in Pathophysiology after pre-review and can be accessed via Internet. The results confirm a statistically significant increased risk for glioma and the risk increases with time from first use of the wireless phone and number of hours for use over the years. The risk is highest on the same side of the brain as the phone has been used, especially in the area with the highest exposure to microwaves, the temporal lobe, which would be expected.
These studies strengthen the 2011 classification by IARC at WHO that the microwave exposure is a ‘Possible human carcinogen’, Group 2B. In fact using the Hill viewpoints on association and causation it should be classified as Group 1, the agent causes human cancer. We have explored that fact in more detail in a previous article. The present results confirm that classification.
Our results have gained interest in many countries after a press release by Reuters and have also been discussed in the Finnish Medical newspaper. However, these worrying results for human health have not been discussed at all in Sweden, so the layman is uniformed about how important it is to avoid such exposure.
