Breast cancer myths: No, antiperspirants do not cause breast cancer

antiperspirantbreastcancer

Four weeks ago, I wrote a post in which I explained why wearing a bra does not cause breast cancer. After I had finished the post, it occurred to me that I should have saved that post for now, given that October is Breast Cancer Awareness Month. The reason is that, like clockwork, pretty much every year around this time articles touting various myths about breast cancer will go viral, circulating on social media like Facebook, Twitter, Pinterest, and Tumblr like so many giant spider-microbes on the moon on Saturday. Sometimes, they’re new articles. Sometimes they’re old articles that, like the killer at the end of a slasher film, seem to have died but always come back for another attack, if not immediately, then when the next movie comes out.

So I thought that this October I should take at least a couple of them on, although I can’t guarantee that I’ll stick to the topic of breast cancer myths for the whole month. After all, our “atavistic oncology” crank (you remember him, don’t you?) is agitating in the comments and e-mailing his latest “challenge” to my dean, other universities, and me. It was almost enough for me to put this post on hold for a week and respond to our insistent little friend’s latest “evidence,” but for now I’ll just tell Dr. Frank Arguello, “Be very careful what you ask for. You might just get it.” Maybe next week. Or maybe on my not-so-super-secret other blog. Or maybe never. Because Dr. Arguello has officially begun to bore me.

In the meantime, I’m going to stick with the original plan, at least for now.

So, first up this week is a myth that I can’t believe that I haven’t covered in depth sometime during the nearly seven years of this blog’s existence, other than in passing a couple of times, even though it’s a topic that deserves its own post. I’m referring to the claim that antiperspirants cause breast cancer. I bet you’ve seen articles like this oldie but not so goodie from über-quack Joe Mercola entitled Are Aluminum-Containing Antiperspirants Contributing To Breast Cancer In Women? or this older and even moldier article from seven years ago entitled Why women should avoid using anti-perspirants that could cause breast cancer or this one from last year entitled Attention Deodorant Users: New Studies Link Aluminum To Breast Cancer. Surprisingly, I haven’t found that many from this year yet. (Maybe the Ebola scare is distracting the usual suspects and diverting their efforts.) The same ones, however, keep reappearing every year, and they’re all based on the same sorts of claims and the same studies. So let’s dig in, shall we?

Gluten-free skin and beauty products: Extracting cash from the gullible

140428_cartoon_046_a18193_p465

Even though yesterday was Easter, and, as unreligious as I am, I was still thinking of taking it easy, there was one target that popped up that I just couldn’t resist. My wife and I were sitting around yesterday reading the Sunday papers and perusing the Internet (as is frequently our wont on Sunday mornings), when I heard a contemptuous harrumph coming from her direction. She then pointed me to an article in our local newspaper entitled Gluten-free beauty products in demand among some customers. Now, I must admit that I haven’t been keeping up with the gluten-free trend, other than how easily it fits within the niche of “autism biomed” quackery, where, apparently, nearly every “biomed” protocol for autistic children demands that gluten be stripped completely from their diets, lest the evil molecule continue to infect them with the dreaded autism. I’ve kept an eye the literature, but haven’t really written about gluten. That’s why I could immediately tell why my wife had called my attention to the article:

Amy Soergel’s lip gloss was making her sick. The problem, she realized, was gluten — hydrologized wheat protein, to be exact. Then she went to the hairdresser who used a shampoo that made her neck burn. Again, it contained gluten.

“There’s hidden gluten in many places you may not consider,” including stamp and envelope glues, toothpaste and lip balms, said Soergel, who has a store, Naturally Soergel’s, near Pittsburgh that caters to people with allergies. Indeed, for people with celiac disease, a bit of gluten that might get swallowed from a lipstick or a stream of shampoo in the shower can be enough to cause illness.

A slew of gluten-free skin care products have come on the market, including items from well-known companies such as Murad, Dr. Hauschka, EO, MyChelle, Suntegrity, Acure and derma-e. Many are sold in Whole Foods and other health food stores. If they’ve been certified by a third-party agency, an icon usually appears on the packaging.

Whole Foods. Of course, it had to be Whole Foods (among others). Let’s take a look at the whole gluten-free movement and then at the end I’ll revisit the question of gluten-free cosmetics and skin products.
