Results (acc. to author)

An increase in the incidence of adult primary intracerebral tumors in four Nordic countries was observed during the time period of 1969 to 1998 that was confined to the late 1970s and the early 1980s and to the oldest age group. This increase coincided with the introduction and more widespread use of computertomography (CT) in the diagnostic procedures. Since 1984, the overall incidence has remained stable during the period after the introduction and wide spread use of mobile phones.
