The study, published in the Journal of the National Cancer Institute, matched Denmark's cell phone records against the Danish Cancer Registry. It followed people who started using cell phones between 1982 and 1995, checking them for a range of cancers in 2002. Even though 52,000 of them had been talking away on cell phones for 10 years or more - back when analog cell phones generally emitted more radiation than digital phones do now - the study found their cancer rate was no higher than that of the general population.

Researchers concluded cell phone use was not linked to a higher risk of tumours in the brain, salivary glands, eyes or around the ears - even for those who had been using cell phones for a decade.

The study is the largest yet to find no cancer risk associated with cell phones and the radiation they emit. Just to be sure, Copenhagen's Danish Cancer Society plans to continue tracking Danish cell phone users until some have used the phones for 30 years.{moscomment}
