Chalk one up for the chatterboxes. In a study spanning 18 years and greater than 350,000 test subjects, researchers in Denmark have found no connection between cellphone usage and brain cancer. The landmark project, performed by Denmark’s Institute of Cancer Epidemiology, was published online last week within the British Medical Journal, and is solely the newest in a sequence 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 which are corresponding to those seen among non-mobile users. Even among long-term cellphone owners (13 years or more), incidence rates weren’t significantly higher than those observed a number of 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 cell phone doesn’t appear to increase the danger of cancers of the brain or central nervous system in adults.” The study’s authors, however, acknowledge some shortcomings of their work, including the exclusion of “corporate subscriptions” — folks that use their mobile devices for work, and who probably use them more heavily than the common consumer. Additionally they recognized the necessity for longer-term research and for more child-specific studies . You could investigate cross-check the object in full, on the coverage link below.
