David Gorski

Orac is the nom de blog of a humble surgeon/scientist who has an ego just big enough to delude himself that someone, somewhere might actually give a rodent's posterior about his copious verbal meanderings, but just barely small enough to admit to himself that few probably will. That surgeon is otherwise known as David Gorski. That Orac has chosen his nom de blog based on a rather cranky and arrogant computer shaped like a clear box of blinking lights that he originally encountered when he became a fan of a 30 year old British SF television show whose special effects were renowned for their BBC/Doctor Who-style low budget look, but whose stories nonetheless resulted in some of the best, most innovative science fiction ever televised, should tell you nearly all that you need to know about Orac. (That, and the length of the preceding sentence.)

DISCLAIMER: The various written meanderings here are the opinions of Orac and Orac alone, written on his own time. They should never be construed as representing the opinions of any other person or entity, especially Orac's cancer center, department of surgery, medical school, or university. Also note that Orac is nonpartisan; he is more than willing to criticize the statements of anyone, regardless of of political leanings, if that anyone advocates pseudoscience or quackery. Finally, medical commentary is not to be construed in any way as medical advice.

I like to point out from time to time that arguably the most striking difference between science-based medicine (and the evidence-based medicine from which we distinguish it) and alternative medicine, "complementary and alternative medicine" (CAM), or (as it's called now) "integrative medicine" is…
I consider posts like the one I'm writing now to be public service, an obligation. There are times when I don't want to do them, when they become so sadly, depressingly repetitive in overall outline (and, unfortunately, likely outcome) that it takes an effort to begin. However, given that October…
I was measured, science-based, and reasonable in yesterday's post about the new American Cancer Society guidelines for screening mammography (which is obviously why that post garnered so few comments, thus teaching me my lesson yet again0, but regular readers know that I can be quite obnoxious and…
One of the things that feels the weirdest about having done the same job, having been in the same specialty, for a longer and longer time is that you frequently feel, as the late, great Yogi Berra would have put it, déjà vu all over again. This is particularly true in science and medicine, where…
If there's one thing that's amusing about the antivaccine movement, it's the disconnect between its members' perception of their own importance and the reality of it, which is that they tend to be a pretty pathetic, risible band. They post their blogs, full of the rage of Dunning-Kruger, thinking…
Two of the great "icons"—if you can call them "great" given that they're icons but hardly "great"—of the antivaccine movement are Andrew Wakefield and Jenny McCarthy. Over the last decade, they have arguably been the most influential people in the antivaccine movement. The reasons are simple. Let's…
If there's one thing I've been consistent about, it's that, however ridiculous all the other woo I routinely discuss here is—homeopathy, reiki, reflexology, I'm talking to you and your friends—herbal medicine and supplements might have value because they might have a physiological effect that is…
Oh, no, Nature. Not you. Not again. It wasn't enough that you were busted shilling for traditional Chinese medicine with a big, glossy advertising supplement a few years ago. I thought you had learned your lesson after that, as you didn't do it again. Maybe I was wrong. Granted, your offense this…
One of the more depressing topics that I regularly write about includes of analyses of news stories of children with cancer whose parents decided to stop science-based treatment (usually the chemotherapy) and use quackery instead. There are, of course, variations on this theme, but these stories…
When last I discussed the cruel sham that is the tide of "right-to-try" laws that has been flowing through state legislatures to become law over the last year and a half. "Right-to-try" laws, as I pointed out when I first noted the earliest ones being promoted in Colorado, Louisiana, Arizona, and…
Last week, in response to the awarding of the Nobel Prize in Physiology or Medicine to Chinese scientist Youyou Tu, who isolated Artemisinin and validated it as a useful treatment for malaria back in the 1970s, I pointed out that the discovery was a triumph of natural products pharmacology, not of…
Over the years, I've frequently made the points that the vast majority of physicians are not scientists and, in fact, that many of them suffer from a severe case of Dunning-Kruger when it comes to science. Even going back to the very early history of this blog, you can find examples, the most…
Yesterday, I wrote about the winner of the Nobel Prize in Physiology or Medicine, Youyou Tu, who, after screening 2,000 herbal treatments from traditional Chinese medicine (TCM) for anti-malaria activity, finally discovered Artemisinin. She isolated it from the plant in which it is found, using…
Earlier this week, the Nobel Prize in Physiology or Medicine was awarded to Youyou Tu for her discovery of the anti-malaria compound Artemisinin, as well as to William C. Campbell and Satoshi Ōmura for their discovery of a novel therapy for roundworm. Artemisinin, as some of you might know, is a…
Anger is an energy, as a certain old punk sang back in the 1980s. It can even be a great motivator, such as when anger overtakes us for injustice or over crimes. Anger, however, is not a particularly good intellectual tool, nor does it help in analyzing science. Which reminds me: J.B. Handley is…
I've written many times about how the relationship between the early detection of cancer and decreased mortality from cancer is not nearly as straightforward as the average person—even the average doctor—thinks, the first time being in the very first year of this blog's existence. Since then, the…
Naturopathy is quackery. I like to start most, if not all, posts about naturopathy with that simple statement. The reasons are simple. First, it's true. Second, most people—including doctors—are unaware of this simple fact. Finally, it irritates naturopaths and their fans. It also has the benefit…
One of the limitations constraining those of us who do human subjects research is that ethical considerations often prevent us from designing our clinical trials in what would be, from a strictly scientific standpoint, in the most methodologically rigorous way. For example, we can't intentionally…
I've spent a lot of time in Cleveland. Indeed, I lived there for eight years in the late 1980s and early 1990s, during which time I completed my surgery residency training, completed my PhD, and, even more importantly, met and married my wife. Even though I haven't lived there for nearly 20 years—I…
A week ago, I noted that one of the stranger and less credible conspiracy theories promulgated by quacks and their believers was still going strong nearly three months after the first death that triggered it, the death of autism quack Jeff Bradstreet, apparently by suicide. Basically, three months…
Yesterday, I wrote about how pediatric neurosurgeon turned presidential candidate Ben Carson is an excellent example demonstrating how the vast majority of physicians and surgeons, even highly accomplished ones admired as being at the top of their professions, are not scientists and how many of…
Early in the history of this blog, I had a running gag that I'd use every now and then. Basically, it involved humorously extravagant descriptions of how I wanted to hide my face behind a paper bag in sheer embarrassment at the antics of fellow physicians, particularly fellow surgeons. Over time,…
Our military veterans deserve the best medical care our nation can offer. Actually, I'd say they're owed it, actually. After all, many of them put themselves in harm's way for this country. Others have suffered grievous injury with permanent sequelae. Still others have paid the ultimate price. For…
Antivaccine quackery is arguably one of the worst forms of quackery. First, the pseudoscientific beliefs undergirding such quackery are based on the fear and demonization of one of the greatest medical advances in the history of the human race, the result of which are children left unprotected…
Ever since late June, I've been intermittently taking note of a new conspiracy theory in the alternative medicine world. It began when notorious autism quack Jeff Bradstreet, one of the longest practicing, most prominent purveyors of the scientifically discredited notion that vaccines cause autism…
Homeopathy is a frequent topic on this blog, for reasons that regular readers no doubt understand all too well by now. Homeopathy is, as I like to call it, again borrowing from Tolkien, The One Quackery To Rule Them All. When it comes to quackery, few can even come close to homeopathy for the sheer…
It just occurred to me that Breast Cancer Awareness Month is fast approaching, not the least of which because I did a Komen event last night as one of the breast cancer experts. I sometimes wonder if I suffer from a bit of the imposter syndrome, because sixteen years on I still sometimes can't…
Regular readers of this blog will find it no surprise that I don't think much of Dr. Mehmet Oz. The reason, of course, is that his daily television show, The Dr. Oz Show, has been a font of misinformation about medicine almost since it began airing six years ago. It's not for nothing that I long…
Note added 9/17/2015: I knew it. The vaccine issue came up during the second debate and Donald Trump repeated basically the same nonsensical antivaccine tropes that he's been repeating for at least eight years. It rather puts the lie to his claim that he listens to experts and changes his opinion…
[Note: My flight home from London was delayed until quite late; so unfortunately another "rerun" is in order. This one's from three years ago, and I actually consider it one of my "classics." It was also originally published at my not-so-super-secret other blog and represents the first time I tried…
