The study, conducted by the Danish Cancer Society, examined the rates of brain tumors among 20-79-year-olds from Sweden, Denmark, Norway and Finland.  According to a researcher for the Danish Cancer Society, “We did not detect any clear change in the long-term time trends in the incidence of brain tumors from 1998 to 2003 in any subgroup.”

Still, researchers admit that longer follow-up studies are required to prove the absence of a link between cell phone usage and brain tumors.  Indeed, the study acknowledges that radio frequency electromagnetic fields emitted from cell phones are a potential “risk factor” for brain tumors, although a “biological mechanism” to explain the potential effects has not been identified.

Thus, because of the high prevalence of mobile phone radio frequency exposure worldwide, longer follow-up studies regarding brain tumor incidence rates are necessary.   For a Free Consultation with one of our Chicago brain injury lawyers, call us at (312) 527-4500.
