Extensive research indicates there’s no increased risk of lung cancer when using talc-based products or for those involved in the manufacture of talc products. [1] Although there’s epidemiological evidence that frequent use of pure talc over the female genital area may increase the risk of ovarian cancer. [2,3] However, a study reviewed in Regulatory Toxicology and Pharmacology stated that “Talc is not genotoxic, it is not carcinogenic when injected into ovaries of rats.… There’s no credible evidence of a cancer risk from inhalation of cosmetic talc by humans.” [4]
