Is talc carcinogenic?

It is a subject of scientific debate whether talc (talcum powder) is carcinogenic. Talc is widely used in cosmetics, baby products and industrial applications.

Concerns about the possible carcinogenicity of talc mainly focus on the presence of asbestos fibers in talc, as talc and asbestos are often found in close proximity in nature. Pure talc (talc that does not contain asbestos) is not considered carcinogenic in studies.

Talcum powder contaminated with asbestos can be carcinogenic. Asbestos is a known carcinogen linked to mesothelioma and other cancers. That is why it is crucial that talcum powder is thoroughly tested and is free of asbestos.

Some studies have found a weak but statistically significant association between the use of talcum powder in the genital area and an increased risk of ovarian cancer. However, this risk remains a matter of debate, and other studies have found no significant association.

An important report on this comes from the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO). The WHO places talc in the 'probably carcinogenic' category. That category also includes red meat, hot drinks and the profession of hairdressing. There is also the category 'carcinogenic'. This category contains substances that are certain to be carcinogenic, such as cigarettes, alcohol, sun rays and asbestos.
