Mixed signal for mobile telephony

According to a study conducted in five northern European countries, there is no clear connection between mobile phone use and malignant brain tumours. The results of the study were published in the web version of the International Journal of Cancer on 19th January.

The study on the possible connection between mobile phone use and the risk of a malignant brain tumour, glioma, was carried out in Denmark, Finland, Norway, Sweden and England. The study showed that mobile phone users were not at an increased risk of developing a glioma.

Regular use of a mobile phone, duration of use, or the cumulative number of calls had no effect on the risk. The only indication of a potential effect was found among mobile phone users who had used a mobile phone for at least 10 years. They were found to have a slightly increased risk of a tumour on the side of the head on which they held the phone.
