According to the links above, talcum powder (which is in baby powder and a host of other products) can contain asbestos and can cause (or increase the risk of obtaining) ovarian cancer when used for feminine hygiene.
Do a web search for talcum powder (without mentioning anything like asbestos or cancer) and see the results!
The takeaway is, don't use products containing talcum powder for feminine hygiene, to prevent diaper rash on babies, etc. Use alternatives instead. In short, don't risk getting asbestos in your system.
