The short answer
Whether talcum powder causes cancer is genuinely uncertain, not settled. Some studies of genital talc use suggested a small increase in ovarian cancer risk; others found no clear link, and results are mixed. Talc that contains asbestos is a known concern, which is why cosmetic talc is meant to be asbestos-free.
The talc–cancer question is genuinely uncertain, with mixed study results.
Some studies of genital talc use suggested a small ovarian cancer risk increase; others found none.
Talc naturally can contain asbestos, a known carcinogen — cosmetic talc is meant to be asbestos-free.
Inhaled talc at work has been studied for lung effects, without strong evidence of a link.

The full explanation.
The claim
Talcum powder, used for personal hygiene and in cosmetics, has been linked in lawsuits and headlines to cancer — especially ovarian cancer from genital use, and lung problems from inhaling it. Unlike some claims, this one reflects a real scientific question that experts continue to study.
What the evidence shows
The evidence is genuinely mixed. Some studies of women who used talc in the genital area suggested a small increase in ovarian cancer risk, while other studies — including some large ones — found no clear link, and researchers debate the quality of the data. One important issue is asbestos: talc in its natural form can be found near asbestos, a known cancer-causing mineral, so cosmetic talc products are required to be asbestos-free. Research on inhaled talc among workers has not shown strong evidence of a lung cancer link.
Why this one is different
Unlike myths with no basis, the talc question involves real, if inconsistent, findings, high-profile lawsuits, and the separate and serious issue of possible asbestos contamination. That mix is why headlines can seem to contradict each other — and why it is fair to say the science is unsettled rather than to declare talc clearly safe or clearly dangerous.
The bottom line
Based on current evidence, a clear causal link between cosmetic (asbestos-free) talc and cancer has not been established, but a small risk from genital use has not been fully ruled out, and research continues. People who prefer to avoid talc can use cornstarch-based powders. If you are concerned about ovarian cancer risk, your care team can discuss your personal risk factors.

Common questions
▸Does talcum powder cause cancer?
The evidence is mixed and the science is unsettled. Some studies suggested a small ovarian cancer risk from genital use; others found no clear link. A clear causal link has not been established.
▸What about asbestos in talc?
Talc can naturally occur near asbestos, a known carcinogen, so cosmetic talc products are required to be asbestos-free. Asbestos itself is a serious, separate concern.
▸Is inhaled talc dangerous?
Studies of workers exposed to talc dust have not shown strong evidence of a lung cancer link, though very high occupational exposures are studied separately.
▸Should I stop using talc?
That is a personal choice. People who prefer to avoid it can use cornstarch-based powders. Talk with your care team if you are concerned about your risk.
