Talcum powder – often referred to as “baby powder” – has been a staple in medicine cabinets for generations, but several studies and a couple of high-profile lawsuits have raised questions about its safety.
Talcum powder is made from talc, a mineral consisting mainly of magnesium, silicon, and oxygen. Because powdered talc absorbs moisture and helps reduce friction, which can cause rashes, it is often used in baby powder, after-shower products and cosmetics. Although some talc in its natural form contains asbestos, a substance known to cause lung cancer, in the United States consumer products that use purified talc have been asbestos-free since the 1970s.
According to the American Cancer Society, research linking talcum powder to cancer has produced mixed findings.
Because many women use talcum powder between their legs or sprinkle it on sanitary napkins, researchers have investigated the possible link between talcum powder and ovarian cancer. Some studies have reported a slightly increased risk, while others have reported no increase. One study suggested genital talcum powder use may slightly increase the risk of endometrial (uterine) cancer in women who are postmenopausal. But other studies have not found such a link. The ACS says more research is needed.
“Cancer has many factors ““ environmental, genetic, lifestyle ““ and these play out differently in each person’s life. To determine whether or not a single particular factor caused a particular cancer is extremely difficult,” says Dr. Christy Sapp, a medical oncologist with OHC. “More research is certainly needed in the area.”
That said, if you have concerns, it’s easy enough to read a product label and, “choose a product that doesn’t contain talc,” she says.
As far as using talc on infants, the American Academy of Pediatrics notes that research shows both talc and cornstarch in baby powder can injure a baby’s lungs and recommends parents who choose to use baby powder pour it out carefully and keep it away from the baby’s face. In general the AAP advises parents to limit the amount of infant-care products they use and not to apply lotions and powders unless indicated for a medical reason.
