In brief: Talc in ovarian ca

One explanation for a possible association between talc and ovarian cancer is that decades ago talcum powder was sometimes contaminated with asbestos, a known carcinogen.

Dr. Ho's explanation is probably the correct one. The studies showing a link are the older ones.

In brief: Talc and Ovarian CA

Talcum powder contains talc (magnesium, silicon & oxygen) and may be used as a powder or found in sanitary napkins, diaphragms or condoms.
Studies linking it to ovarian cancer have given mixed results. A compilation of 16 studies (all done before 2003) found a 30% increase in ovarian cancer risk among users. This would theoretically raise a woman's lifetime risk from 1.4% to 1.8% - still very low.
