[Editor's note: It's a holiday here in the U.S.; consequently, here is a "rerun" from my other super not-so-secret other blog. It's not a complete rerun. I've tweaked it a bit. If you don't read my other blog, it's new to you. If you do, it's partially new to you. See you all next week with brand spankin' new material. It also (Ih hope) complement's Scott's excellent post from Thursday discussing the same issue and the same paper, but from a different perspective.]
As a cancer surgeon specializing in breast cancer, I have a particularly intense dislike reserved for cancer quacks, which I have a hard time containing at times when I see instances of such quackery applied to women with breast cancer. I make no apologies. These women are, after all, the type of patients I spend all my clinical time taking care of and to whose disease my research has been directed for the last 13 years or so. That’s why I keep revisiting the topic time and time again. Unfortunately, over the years, when it comes to this topic there’s been a depressing amount of blogging material. Indeed, Scott Gavura took a bite out of this particularly rotten apple just a few days ago. Even though he handled the discussion quite well, I thought it would be worthwhile for a breast cancer clinician to take a look. Our perspectives are, after all, different, and this is an issue that, from my perpective, almost can’t be discussed too often.
One question that comes up again and again is, “What’s the harm?” Basically, this question boils down to asking what, specifically, is the downside of choosing quackery over science-based medicine. In the case of breast cancer, the answer is: plenty. The price of foregoing effective therapy can be death; that almost goes without saying. In fact, it can be a horrific and painful death. It is, after all, cancer that we’re talking about. Aside from that, however, the question frequently comes up just how much a woman decreases her odds of survival by avoiding conventional therapy and choosing quackery. It’s actually a pretty hard question to answer. The reason is simple. It’s a very difficult topic to study because we as physicians have ethics. We can’t do a randomized trial assigning women to treatment or no treatment, treatment or quacke treatment, and then see which group lives longer and by how much. If a person can’t see how unethical that would be without my having to explain it, that person is probably beyond explanations. (As an aside, I can’t help but point out that a randomized trial of not vaccinating versus vaccinating is unethical for exactly the same reason; physicians can’t knowingly assign subjects to a group where he knows they will suffer harm. There has to be clinical equipoise.) There’s no doubt that foregoing effective treatment causes great harm.
