Two Cancers Have Links With Talc. An Expert Explains The Science.
An expert explains the potential links between talc use and ovarian and lung cancers, citing asbestos contamination and recent WHO warnings.Summary
Recent lawsuits, including a $40 million judgment against Johnson & Johnson, have highlighted concerns about the link between talc powder and cancers like ovarian cancer and mesothelioma. Talc, a naturally occurring mineral, has been questioned due to potential asbestos contamination during mining, a known carcinogen. While manufacturers have attempted to produce asbestos-free talc, concerns remain about historical contamination and testing practices.
Scientific evidence suggests a possible weak link between talc use and some types of ovarian cancer, particularly with frequent genital use, though studies have yielded mixed results. However, studies have not found a link between talc and uterine or cervical cancer. Talc contaminated with asbestos is linked to lung cancer, but cosmetic use doesn't appear to pose the same risk as inhalation in industrial settings.
The World Health Organization (WHO) now classifies talc as “probably carcinogenic,” the second-highest risk level for cancer. Experts recommend limiting or stopping talc use if concerned about potential risks, weighing potential harms against benefits, especially for long-term users.
