I would like to inform about the incidence increase of central nervous system (CNS) tumors in Sweden. In a letter to the Editor of Pathophysiology I noticed that brain cancer has been increasing most in the more sparsely populated regions of Sweden, while the rest of the CNS tumors have increased most in the more densely populated regions. See: Hallberg Ö. Increasing incidence of brain tumors in sparsely populated areas. Pathophysiology, 14 (2) 2007 (in press)

It is known that the output power from mobile phones is larger in sparsely populated areas due to longer average distances to base stations.
