Mammography’s Failings: Rage Against the Machine

I was dismayed but not surprised by the recent news of mammography’s failings. As most of you know, per the NYT “one of the largest and most meticulous studies of mammography ever done…added powerful new doubts about the value of the screening test [mammography] for women of any age.”

But what shocked my socks off was the headline appearing in the same paper less than a week later “A Fresh Case for Breast Self-Exams.” The upbeat article highlighted what the writer called the study’s “nugget of hope,” which was that physical breast exams may be “as good as or better than regular mammograms.”

I hear the ’80s calling. They want their breast cancer screening method back.

Previous studies indicate breast self-exams are no better than mammography when it comes to stemming the tide of breast cancer deaths. I covered the topic for Time in 2008. The Cochrane Collaboration (an international organization that evaluates medical research) had just reviewed studies of breast self-exam that involved nearly 400,000 women. Their conclusion? Breast self-checks had no benefit. 

So, before we roll back the clock, before we go back to touching our breasts out of fear, before we give women deja vu, I’d like to hit the pause button.

Can we all please take a collective moment of silence to mourn the failed promise of mammography?

Regardless of whether you choose to believe in mammography (like Amy Robach over at ABC) or you are a dubious science reporter twice screwed by breast cancer (like me), last week’s news was a devastating blow.

Then I’d like to break the silence with a giant primal scream. Because when I think of the tens of billions of dollars spent chasing the “early detection myth,” I can’t help but think of how those billions might have made a difference for the hundreds of thousands of women who are no longer with us. And that makes me hoppin’ mad.

So. Please take a moment of silence and then follow it up with a big scream.

On Pink Washing: Dear Food Makers, Please Shut Up.

Pink washing health claims on food packaging are obnoxious. They are confusing, misleading, and (often) inaccurate. As a science journalist, I know that 99.9 percent of these health claims are hogwash, and I find it morally offensive that food marketers prey on people’s fear of disease to sell products. I actively avoid buying products with health claims or pink washing. So, imagine my surprise when I opened a new container of miso and found a giant health claim lurking beneath the lid. Sneak attack!

MisoSoup

Nothing kills my appetite more than a pink-ribbonly reminder of my mortality. Thanks Mr. Miso!

I will give them a tiny prop for including a study citation, even though its presence could be construed as manipulative because it adds superficial credence to the claim. So, I walked my anger right over to PubMed and looked up the study. A tiny part of me (the sucker part) hoped the health claim was true. But a much bigger part of me (the pompous part) wanted to feel “right” and, therefore, justified in my anger. Guess which part won?

Here’s the miso dish: In 1990, 21,000 Japanese women filled out diet questionnaires that included a question about miso soup. (BTW: Diet questionnaires are notoriously inaccurate because, really, who can remember what they ate for breakfast? Much less for breakfast six weeks ago?) Researchers followed the women for nine years and charted how many got breast cancer. In the end, fewer cases of BC popped up in those women who (reportedly) ate 3+ bowls of miso soup a day.

A few caveats: the study’s small sample size means its accuracy is suspect; miso’s magic only applied to postmenopausal women (bummer for me); I live in the West, not Japan, so my confounding factors are enormous; and, finally, who eats 3 bowls of miso soup a day for years on end? Not me.

When it comes to health claims, even those with citations, don’t be a sucker. Health claims on food packages are nothing but savvy marketing with a scientific sheen. I can only hope that, if we all vote with our dollars, food makers will get the message that we don’t want our fears manipulated at the grocery store.
