Jenny McCarthy, Jim Carrey, and “Green Our Vaccines”: Anti-vaccine, not “pro-safe vaccine”

Last week, there was a rally in Washington, D.C. How many people actually attended the rally is uncertain. The organizers themselves claim that 8,500 people attended, while more objective estimates from people not associated with the march put the number at probably less than 1,000. Of course, such wide variations in estimates for the attendance at such events are not uncommon. For...

Early detection of cancer, part 2: Breast cancer and MRI

Note: If you haven’t already, you should read PART 1 of this two-part series. It defines several terms that I will be using in this post, and I don’t plan on explaining them again, given that they were explained in detail in Part 1. Of course, if you’re a medical professional and already know what lead time bias, length bias, and stage...

Monkey business in autism research

NOTE: I had originally planned on posting Part II of a series on cancer screening. However, something came up on Friday that, in my estimation, requires a timely response. I should also inform readers that, because next Monday is a holiday here in the U.S., I haven’t yet decided whether I will be doing a post next week or not. Stay tuned...

The early detection of cancer and improved survival: More complicated than most people think

“Early detection of cancer saves lives.” How many times have you heard this statement or something resembling it? It’s a common assumption (indeed, a seemingly common sense assumption) that detecting cancer early is always a good thing. Why wouldn’t it always be a good thing, after all? For many cancers, such as breast cancer and colon cancer, there’s little doubt tha early...

The Ethics of “CAM” Trials: Gonzo (Part I)

Blogger’s note: This blog, which is rough going in places, will be presented in either 2 or 3 parts (I won’t know which until next week). I’ll post a part each week until it is complete, but due to overwhelming popular demand I promise to maintain the every-other-week posting of the far more amusing Weekly Waluation of the Weasel Words of Woo/2. Introduction On Feb. 25,...

Thoughts on Neuroplasticity

I recently read a fascinating book, The Brain That Changes Itself by Norman Doidge. He describes case histories and research indicating that the brain is far more malleable than we once thought. We used to think each function was localized to a small area of the brain and if you lost that area of brain tissue the function was gone forever. We once thought...

Misleading Language: the Common Currency of “CAM” Characterizations Part II

Background I promised readers the “Advanced Course” for this week, which undoubtedly has you shaking in your boots. Fear not: you’ve already had a taste of advanced, subtle, misleading “CAM” language, and most of you probably “got” it. That was R. Barker Bausell’s analysis of how homeopathy is “hypothesized to work.” In the interest of civility, let me reiterate that I don’t...

Bad scientific arguments in the service of animal rights activism

One of the greatest threats to the preclinical research necessary for science-based medicine today is animal rights activism. The magnitude of the problem came to the forefront again last week with the news that animal rights terrorists tried to enter the home of a researcher at the University of California Santa Cruz (UCSC) whose research uses mice to study breast cancer and...
