Why Avoid Talc in Body Powder

Talc is closely related to the potent carcinogen asbestos. Talc particles have been shown to cause tumors in the ovaries and lungs of cancer victims. 

For the last 30 years, scientists have closely scrutinized talc particles and found dangerous similarities to asbestos. Responding to this evidence in 1973, the FDA drafted a resolution that would limit the amount of asbestos-like fibers in cosmetic grade talc. However, no ruling has ever been made and today, cosmetic grade talc remains non-regulated by the federal government. This inaction ignores a 1993 National Toxicology Program report which found that cosmetic grade talc, without any asbestos-like fibers, caused tumors in animals. Clearly with or without asbestos-like fibers, cosmetic grade talcum powder is a carcinogen.

As we say here at The Creekside, “Why take the risk?”

Ovarian cancer It has been suggested that talcum powder might cause cancer in the ovaries if the powder particles (applied to the genital area or on sanitary napkins, diaphragms, or condoms) were to travel through the vagina, uterus, and fallopian tubes to the ovary. Several studies in women have looked at the possible link between talcum powder and cancer of the ovary. Findings are mixed, with some studies reporting a slightly increased risk and some reporting no increase.

Lung cancer Some studies of talc miners and millers have suggested an increased risk of lung cancer and other respiratory diseases, while others have found no increase in lung cancer risk. These studies have been complicated by the fact that talc in its natural form contain varying amounts of asbestos. When working underground, miners may also be exposed to other substances that might affect lung cancer risk, such as radon.

Other cancers One recent study suggested genital talcum powder use may slightly increase the risk of endometrial (uterine) cancer in women who are past menopause, but further studies are needed to explore this possible link.

Another worthy source of information quoted from the University of Illinois at Chicago:

ACTIONS YOU CAN TAKE:

1. Do not buy or use products containing talc. It is especially
important that women not apply talc to underwear or sanitary pads.
2. Contact your pediatrician and/or local hospital and find out if they
have a policy regarding talc use and infants.
3. Write to the FDA and express your concern that a proven carcinogen
has remained unregulated while millions of people are unknowingly
exposed.
