Link Found Between Powder Use and Ovarian Cancer SEATTLE, March 3, 1997 -- Women who use powder products in genital areas may have an increased risk for ovarian cancer report researchers in a study published in the March 1 issue of the American Journal of Epidemiology. "Overall, there was a 50% increase in risk for developing ovarian cancer for women who use one or more of four possible methods of genital powder application," said Linda Cook, an epidemiologist with the Fred Hutchinson Cancer Research Center and the University of Washington. Cook, who led the research team, said the group found the highest risk (90%) among women who use genital deodorant sprays and a slightly lower, but increased risk (6%) in women who had a history of perineal powder dusting after bathing. The study compared 834 women from King, Pierce and Snohomish counties between the ages of 20 and 79 years. A total of 313 of these women, identified from records of the Cancer Surveillance System of western Washington, had been diagnosed with borderline or invasive epithelial tumors in the ovaries. The other 521, selected by random digit dialing, had no history of ovarian cancer. Investigators interviewed all participants about the storing of diaphragms in powder, dusting perineal areas with powder after bathing, powdering of sanitary napkins, and the use of genital deodorant sprays. Those who used the products were also asked about the duration and frequency of use and the types of powders used. "Even though we found the highest increase for risk of ovarian cancer in women who dust with powder after bathing, we did not see a clear pattern of increasing risk with longer durations of use," said Cook. "However, the elevation in risk associated with the use of genital deodorant spray was highest among women who used the sprays for longer periods of time." Also, investigators did not see any increase in risk for developing an ovarian tumor associated with the storing of diaphragms in powder or powdering of sanitary napkins. In addition, there was no specific type of powder identified as contributing to an increase in risk, although there was a suggestion of elevated risk associated with any use of talcum powder and bath or body powders. Other studies have reported similar results. This study was the first to look at the relationship between the use of genital deodorant spray and ovarian cancer risk. Investigators feel these preliminary results require further confirmation in other studies. This study was funded by a grant from the National Cancer Institute and by the Cancer Surveillance System of the Fred Hutchinson Cancer Research Center. The Hutchinson Center is an independent, non-profit research institution dedicated to the development and advancement of biomedical technology to prevent and eliminate cancer and other potentially fatal diseases. It is one of 27 National Cancer Institute-designated comprehensive cancer centers in the country and the only one in the Northwest. E-mail this page to a friend or colleague!
