MedicalResearch.com Interview with: Theresa S. Emory MD Department of Pathology, Peninsula Pathology Associates Newport News, VA MedicalResearch.com: What is the background for this study? What are the main findings? Response: Cosmetic talc products can contain asbestos, which is the primary cause of malignant mesothelioma. We investigated 75 individuals with malignant mesothelioma, whose only known exposure to asbestos was repeated exposures to cosmetic talcum powder. 83% of the individuals were female and several occurred in barbers/cosmetologists. 16% occurred in individuals younger than 45 years old, and on average the subjects were 11 years younger than predicted, based on SEER data. The asbestos fibers in tissue samples that were examined in 11 cases were identical (anthophyllite and tremolite) to those identified in cosmetic talc. (more…)

MedicalResearch.com Interview with: Clarice Weinberg, Ph.D. Deputy Branch Chief Biostatistics and Computational Biology Branch National Institute of Environmental Health Sciences National Institutes of Health Research Triangle Park, NC 27709 MedicalResearch.com: What is the background for this study? What are the main findings? Response: A number of studies have reported a link between genital use of talc powders and ovarian cancer. We wondered whether the practice of douching could contribute to that risk by moving fibers and chemicals into and up the reproductive tract. We are carrying out the Sister Study, a large cohort study that enrolled more than 50,000 women who each had a sister diagnosed with breast cancer and who are consequently at increased risk of ovarian cancer. During the Sister Study enrollment interview, we asked each of them about their douching and use of talc in the previous 12 months. During approximately 6 years of follow up, 154 participants developed ovarian cancer. Our statistical analyses did not show any relationship between talc use and risk of ovarian cancer, but we estimated that women who had said they douched had almost double the risk for ovarian cancer compared to women who did not douche.
