Given that there are distinct demographics that use this powder disproportionately (e.g. professional gymnasts and climbers), shouldn't an increased cancer rate be very visible?
The demographic that was harmed disproportionately was actually women, poor black women in the south in particular. There were campaigns that promoted talc as a way for poor women to "stay fresh" for cheap. You'd line your panties with it. It was common, and something that was often done for decades starting at a very young age. This use case is the where the link between talc exposure and ovarian cancer comes from.
