Is cosmetic talc related to ovarian cancer?

There is no definitive answer to this question because the research on the subject is ongoing. Some studies have found a correlation between talc use and ovarian cancer, while other studies have not found a correlation.

What is currently known is that if talc becomes attached to your ovaries, it can cause irritation. This irritation can then lead to the development of ovarian cancer. So, while there is still some uncertainty about whether or not talc causes ovarian cancer, it's probably best to err on the side of caution and avoid using it as a cosmetic ingredient.
