Talc claims proceed on two theories: that perineal talc use causes ovarian cancer, and that talc contaminated with asbestos caused mesothelioma. The scientific support differs substantially between them.
Testing methodology for asbestos in talc is heavily contested.

Talcum Powder Litigation, Talc Claims
Why it Matters?
The two theories require entirely different defenses. The mesothelioma theory turns on whether the specific product contained asbestos, which is a testing and historical sourcing question. The ovarian cancer theory turns on general causation, where the epidemiology is mixed and defense arguments about recall bias in case-control studies are substantive. Treating them as one litigation misses that they succeed and fail on different grounds.
