The study, performed by the Danish Cancer Society and documented in
the Journal of the National Cancer Institute, studied brain cancer
rates in Scandinavian countries over a period of 30 years. It is likely
ongoing, but they have issued the results of the 30-year analysis, not
having found “any clear change in the long-term time trends in the
incidence of brain tumours.” The critical period in the mid-nineties
when cellular use really spiked was the focal point for their study,
and they found that while there has been a constant increase in glioma
diagnosis since the 70s, and any deviations from the slow increase are
explainable by other means than mobile use.
Like most studies, this one does not prove anything, but it
would be coincidental indeed if every Scandie managed to avoid brain
cancer by chance, while also happening to be among the most
mobile-friendly areas on Earth.
