Abstract: To investigate whether use of electric blankets, one of the largest sources of electromagnetic field exposure in the home, is associated with the risk of female breast cancer, the authors analyzed data from a population-based US case-control study. The 2,199 case patients were under age 55 years and had been newly diagnosed with breast cancer between 1990 and 1992. The 2,009 controls were frequency-matched to cases by 5-year age group and geographic area. There was little or no risk associated with ever having used electric blankets, mattress pads, or heated water beds among women under age 45 years (adjusted odds ratio = 1.01, 95% confidence interval 0.86-1.18) or among women aged > or =45 years (adjusted odds ratio = 1.12, 95% confidence interval 0.87-1.43). There was no substantial variation in risk with duration of use; with whether the appliance was used only to warm the bed or used throughout the night; with menopausal status; or with the cases' hormone receptor status or stage of disease. Potential breast cancer risk factors that were associated with electric blanket use did not substantially confound the associations under investigation. These data do not support the hypothesis that electric blanket use increases breast cancer risk among women under age 55 years.
