Cell phones don't increase chances of brain cancer

mclearn writes: A very large, 30-year study of just about everyone in Scandinavia shows no link between mobile phone use and brain tumours, researchers reported on Thursday. Even though mobile telephone use soared in the 1990s and afterward, brain tumours did not become any more common during this time, the researchers reported in the Journal of the National Cancer Institute. Some activist groups and a few researchers have raised concerns about a link between mobile phones and several kinds of cancer, including brain tumours, although years of research have failed to establish a connection.

"From 1974 to 2003, the incidence rate of glioma (a type of brain tumor) increased by 0.5 per cent per year among men and by 0.2 per cent per year among women," they wrote. Overall, there was no significant pattern.
