Chalk one up for the chatterboxes. In a study spanning 18 years and more than 350,000 test subjects, researchers in Denmark have found no connection between cellphone usage and brain cancer. The landmark project, carried out by Denmark’s Institute of Cancer Epidemiology, was published online last week in the British Medical Journal, and is just the latest in a series of similarly optimistic studies. Of the 358,403 cellphone owners examined, only 356 were found to have a brain tumor, while 856 were diagnosed with cancer of the central nervous system — percentages that are comparable to those seen among non-mobile users. Even among long-term cellphone owners (13 years or more), incidence rates were not significantly higher than those observed among the general population. Hazel Nunn, head of evidence and health information at Cancer Research UK, described the study as “the strongest evidence yet that using a mobile phone does not seem to increase the risk of cancers of the brain or central nervous system in adults.” The study’s authors, however, acknowledge some shortcomings in their work, including the exclusion of “corporate subscriptions” — people who use their mobile devices for work, and who probably use them more heavily than the average consumer. They also recognized the need for longer-term research and for more child-specific studies. You can check out the article in full, at the coverage link below.
