Although talcum powder is a staple in the bathroom cabinets of many American women, its potential link to ovarian cancer can be traced back more than 40 years. Scientific studies have been published in a number of prominent journals worldwide.
Researchers first pointed to a possible connection in 1971 when a British study published in the Journal of Obstetrics and Gynaecology found talc particles “deeply embedded” in 10 out of 13 biopsied ovarian tumors.
That study was followed by a 1982 publication in the journal Cancer, which found that women who dusted their genital area or feminine napkins with talc were three times more likely to develop ovarian cancer than those without talc exposure.
More than 20 other studies have been performed over the years and most all found that women who used talc near their genitals were at an increased risk for ovarian cancer. In 2013, a genital powder cancer study published in the journal Cancer Prevention Research showed women who dusted their genital area with talcum powder had a 20 to 30 percent greater risk than women who did not use talc products for intimate personal hygiene.
This is not an exhaustive list of all studies and events related to talcum powder and cancer. Johnson & Johnson ― the largest maker of health care products ― has been aware of the research establishing a cause-effect relationship for decades, yet the product is still being sold and marketed as a feminine hygiene product with NO warning on its labels about the potential cancer risk.
