Association of powder use in the genital area with risk of ovarian cancer

Researchers delved into prospective observational data as part of an investigation into the suspected correlation between ovarian cancer risk and application of powder to the genital area.

Researchers delved into prospective observational data as part of an investigation into the suspected correlation between ovarian cancer risk and application of powder to the genital area. The pooled sample included 252,745 participants from four large, U.S.-based health study cohorts, 38% of whom acknowledged ever using powder in the manner described. Ovarian cancer developed in 2,168 of the women during followup of a median 11.2 years, for an incidence rate of 58 cases per 100,000 person-years. The hazard ratio between ever users and never users was 1.08, which was not considered to be statistically significant. The investigators concede, however, that their research may have been underpowered.
