You could say the same about anything and everything, including oxygen. Nothing in the world is 100% safe. The research is nowhere near conclusive and, in the study that is quoted raises the risks by a third that stat is rendered almost meaningless by the miniscule size of the original Relative Risk. I suspect that this case will drag on for decades, more research will be done and talc will have been replaced by somethign else by the time the data is in.
Until then we each have to decide where do you draw the line? One US court case that is being challenged? One now struck off doctor and his MMR beliefs? Where we have access to data it is quite simple to see what the more real, every day dangers are without flinching at all sorts of shadows.
And if you read the info available you can see that this woman used talc for decades, yet the type that included asbestos has not been available for decades:
In the past, talc contained asbestos, which is proven to cause cancer. All talcum powder used in products for humans has been asbestos-free since the 1970s, according to the American Cancer Society.
So, I shall continue with my occasional use of talc under my knicker elastic and bra without fear!
