The meta-analyses of the available human studies in the peer-reviewed literature indicate a consistent and statistically significant positive association between perineal exposure to talc and ovarian cancer. Further, available data are indicative of a causal effect. (P.iii)

“The results of this review indicate that perineal talc use is associatedwith a 24%–39% increased risk of ovarian cancer. While the results ofcase–control studies are prone to recall bias, especially with intensemedia attention following the commencement of litigation in 2014,the confirmation of an association in cohort studies between perinealtalc use and serous invasive ovarian cancer is suggestive of a causalassociation.”

March 12, 2019: Hearing on Health Risks of Carcinogens in Consumer ProductsHouse Committee on Oversight and Reform
Subcommittee on Economic and Consumer Policy
• My review identified 38 high-quality epidemiologic studies conducted over the past 40 years. These studies asked women about their use of talcum powder products in the genital area, and tested associations with risk of ovarian cancer. Together, these studies included over 14,000 women with epithelial ovarian cancer (the most common type) and an even greater number of women without ovarian cancer.
• Summarizing data from all of the published studies consistently shows that women who had ever used talcum powder products in the genital area had a statistically significant 22-31% increased risk of developing epithelial ovarian cancer compared with women who had never used them.
• These combined analyses showed that increasing amount of exposure to talcum powder products in the genital area resulted in increasing risk of developing epithelial ovarian cancer.
