Talc is ‘probably’ cancer-causing

LYON:

The World Health Organization’s cancer agency on Friday classified talc as “probably carcinogenic” for humans, however an outside expert warned against misinterpreting the announcement as a “smoking gun”.

The decision was based on “limited evidence” talc could cause ovarian cancer in humans, “sufficient evidence” it was linked to cancer in rats and “strong mechanistic evidence” that it shows carcinogenic signs in human cells, the WHO’s International Agency for Research on Cancer (IARC) said.

Talc is a naturally occurring mineral which is mined in many parts of the world and is often used to make talcum baby powder.

Most people are exposed to talc in the form of baby powder or cosmetics, according to the Lyon-based IARC.

But the most significant exposure to talc occurs when talc is being mined, processed or used to make products, it added.

The agency said there were numerous studies which consistently showed an increase in the rate of ovarian cancer in women who use talc on their genitals.
