Primary brain cancer in adults and the use of common household appliances: a case-control study

Increasing attention has been paid to whether low frequency non-ionizing radiation causes human cancers. In an ongoing case-control study of primary malignant brain cancer in adults, we examined the risk associated with common household appliances. Subjects were questioned about their use of personal computers, electric heaters, electric hair dryers, electric razors, and other appliances. No risk of brain cancer was observed with regular use of any of these items. Although magnetic field exposures were not measured, this study does not implicate the use of electric appliances in adult astroglial cancers.
