Key PointsQuestionIs use of powder in the genital area associated with the risk of developing ovarian cancer? FindingsIn this analysis that pooled data from 4 cohorts with a total of 252 745 women, the hazard ratio for the association between self-reported ever use vs never use of powder in the genital area and incident ovarian cancer was 1.08 (95% CI, 0.99-1.17). MeaningAmong women from 4 prospective cohorts, there was not a statistically significant association between use of powder in the genital area and ovarian cancer, but the study may have been underpowered to identify a small increase in risk.
