A long term Scandinavian study of cell phone users has now given many the results they have been hoping for – long term usage shows no significant increase in cancer risks.

The slashdot item speaks of a negligible increase of brain tumors and was able to peg the actual incidence rates over time –

mclearn sends in news of “a very large, 30-year study of just about everyone in Scandinavia” that shows no link between mobile phone use and brain tumors. “Even though mobile telephone use soared in the 1990s and afterward, brain tumors 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 tumors, 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.”

The fact that the testing was done in Scandinavia is probably a very good thing, as the people of that region tend to be much higher users of cell phones than most anywhere else on earth. If risks don’t show higher incidence there the chances are good that we’ll never have problems with usage.

Also, each new generation of cell towers operate at higher efficiency (aided by fully digital transmission) and therefore newer cell phones use considerably less power – that is the main reason for ever increasing battery life times. It is a win-win, with short and long term benefits.
