Study Finds Association Between Genital Talc Use and Increased Risk of Ovarian Cancer

  • Focus: This study examines the association between the use of intimate care products, specifically genital talc and douching, and the risk of hormone-related cancers such as ovarian, breast, and uterine cancers, correcting for potential biases like recall bias and exposure misclassification.
  • Population: The study involved 50,884 women from the Sister Study cohort, all of whom had a sister diagnosed with breast cancer, providing a unique perspective on the genetic predisposition to hormone-related cancers.
  • Main Takeaway: Genital talc use was found to be positively associated with the risk of ovarian cancer across multiple scenarios, even after adjusting for potential reporting biases and misclassification. The association was particularly strong among women who used talc frequently or especially during periods of significant hormonal changes or reproductive activity.
  • Significance: These findings contribute significant insights into the ongoing debate about the safety of intimate care products and underscore the need for further research and potential reevaluation of these products' safety.
