MANCHESTER, England, Feb. 18 (UPI) -- Cellphone use does not appear to increase the risk of developing brain tumors by any significant amount, researchers in Britain say.
Lead researcher Dr. Frank de Vocht of the University of Manchester and colleagues used data from the Office of National Statistics to look at trends in rates of newly diagnosed brain cancers in England from 1998 to 2007 -- to related to the period 1990 to 2002 when British cellphone use increased from 0 percent to 65 percent of households.
