Talcum powder and ovarian cancer

This is a horrifying story. If you’re lucky, there’s no asbestos in your powder — but it might kill you anyway. Fortunately for me, since we grew up poor, we’d put cornstarch in a sock, tie it up and dab ourselves with it when we were hot and sweaty. Hopefully, that won’t kill us!

Suspicions about talc and ovarian cancer go back decades. In 1971, British researchers analyzed 13 ovarian tumors under a microscope and found talc particles ‘’deeply embedded” in 10.

In 1982, the journal Cancer published the first study showing a statistical link between genital talc use and ovarian cancer. Soon after, lead author Dr. Daniel Cramer, a gynecologist and Harvard Medical School professor, was visited by a senior scientist from J&J. He “spent his time trying to convince me that talc use was a harmless habit,” Cramer recalled in a document filed in court, “while I spent my time trying to persuade him … that women should be advised of this potential risk.”

Altogether, about 20 epidemiological studies have found increased rates of ovarian cancer risk for women using talc for hygiene purposes, though some studies have found no association. One report, published by Cramer and several co-authors in 1999, said talc use could be the cause of about 10 percent of ovarian cancers in the U.S.–or some 2,000 cases per year. “Balanced against what are primarily aesthetic reasons for using talc in genital hygiene, the risk benefit decision is not complex,” the study said. “Appropriate warnings should be provided to women about the potential risks of regular use of talc in the genital area.”

In response to such findings, the Cancer Prevention Coalition, an advocacy group, asked the Food and Drug Administration in 1994 to require warnings against talc use for genital hygiene. The agency said it lacked evidence to require warnings, and J&J refused to issue them voluntarily.

Instead, the company and its allies circled the wagons. In 1992, the cosmetic and fragrance association launched a Talc Interested Party Task Force to develop talking points and find experts to rebut studies linking talc to ovarian cancer.

But some statements by the trade group were “inaccurate, to phrase it euphemistically,” a consultant for J&J warned. In two 1997 letters to company officials (here and here), toxicologist Alfred P. Wehner attacked statements that “the scientific evidence did not demonstrate any real association between talc use in consumer products and ovarian tumors.”

“There are at least 9 epidemiological studies published in the professional literature describing a statistically significant (albeit weak) association between hygienic talc use and ovarian cancer,” Wehner wrote.

“Anybody who denies this risks that the talc industry will be perceived by the public like it perceives the cigarette industry: denying the obvious in the face of all evidence to the contrary. This would be a particularly tragic misperception in view of the fact that the industry does have powerful, valid arguments to support its position.”

One thought on “Talcum powder and ovarian cancer

  1. Interesting, but how do they think it gets in those ovaries? Is it inhaled by the mother? Is it transferred thru the skin of the groin or genital membranes? Is it inhaled by the women when they were babies? I had five siblings, and I must have inhaled a couple bottles worth over the first twelve years of my life when there was almost always at least one kid in diapers. If it gets into ovaries, what else is it getting into? Prostates? Breasts? Brains? Livers? Kidneys & bladders? Thyroids? Lungs? Hearts? I can’t believe it just targets one organ in one sex’s bodies.
    I get so pissed off at people at the gym who use that kind of shit in their socks, or use aerosol deodorants. I’m sure it’s worse in the women’s locker room with all their nonsense hair products. You say anything about them exposing everyone to their chemicals and you always get a brush off, with a statement that if it was dangerous it wouldn’t be legal (as if), or else that “everything” will kill you (as though there is no point in trying to minimize your risks, or that you have no responsibility to other humans in the world as long as you don’t even care enough about your own health).
    When I start thinking about all that shit, I pretty much end up feeling like the human race pretty much deserves all the shit it gets.
