Dec. 3, 2009 -- Scientists say they could find no substantial change in the
incidence trend of brain tumors among a study group of 60,000 people five to 10
years after cell phone usage rose sharply in the countries where they
lived.
Cell phones have been mentioned for years as possible causes of brain
tumors, but the new study, published in the Dec. 3 online issue of the
Journal of the National Cancer Institute, found no cell phone-related
increase during this study period.
Researchers from Denmark, Finland, Norway, and Sweden say they found that
the incidence of brain tumors in the studied population of people from the four
countries remained stable, decreased, or showed only a gradual increase that
started before the introduction of the wireless devices between 1974 and
2003.
