No proof of mobile cancer risk, major study concludes

Using a mobile phone does not appear to increase the risk of developing certain types of brain cancer, the largest study of its kind has concluded.

Analysis of more than 10,000 people by the International Agency for Research on Cancer (IARC) found no relationship between years of use and risk. There is no known biological mechanism by which mobiles could cause cancer, but there has been public concern. It is hoped this study will allay some anxieties, as research continues.

The overall rate of brain cancer has not risen in countries where use has long been prevalent - like Sweden, and studies have mostly found no evidence of an increased risk. This latest research is consistent with this.

The 20m euro (£17m) Interphone study, which received some funding from the mobile industry, involved more than 5,000 men and women from 13 countries who had been diagnosed with one of two types of brain cancer - glioma and meningioma - between 2000 and 2004. These cancers, both rare, were judged to be among the most likely to be influenced by phone use.

The patients were asked to record their mobile phone usage, and then the results were compared with adults of similar age, sex and background who did not have the disease. Some had been using their phones for more than a decade, making this one of the longest-ranging studies to date.
