Talc deposits are often located near asbestos ore since the two minerals are chemically similar. This triggered fears in the 1960s that mined talc could be contaminated with asbestos and cause cancer.>Home talc products have been asbestos-free since the 1970s but the debate continues today. This topic has received increasing media attention due to ongoing litigation in the US.>Studies on a possible link between body talcum powder and cancer have produced mixed results.>SummaryThe current evidence is insufficient to conclude that the use of talcum powder on the external genitals is linked to ovarian cancer, endometrial cancer or mesothelioma. If there is a risk, it is likely to be small. While the matter remains unresolved, women who wish to take all precautions could avoid the use of genital powders or opt for powders that contain cornstarch instead of talc.
