In recent years, women have taken talcum powder manufacturers to court over concerns that the use of the product in the genital area could cause ovarian cancer. Now, a new study finds no meaningful association between using talc-based or other powders and ovarian cancer.
Researchers from NIH’s National Institute of Environmental Health Sciences and the National Cancer Institute conducted the largest study to date of genital powder use and ovarian cancer. The study, published Tuesday in JAMA, used data from 252,745 women who answered questions about whether they used powder on their genitals. This was a pooled analysis of four large studies gathering data about the frequency and length of time women used the powder.
According to epidemiologist Katie O’Brien who headed the study, women report applying the powder either directly on their genital area or on sanitary napkins, tampons, underwear or diaphragms. O’Brien doesn’t know exactly which type of powder women used. It could have been talcum powder alone, cornstarch alone or a combination of both.
