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.

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.
