“Liquid biopsies” for cancer screening: Life-saving tests, or overdiagnosis and overtreatment taken to a new level?

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 complexities and overpromising of various screening modalities designed to detect disease at an early, asymptomatic...

Donald Trump and the dangerous vaccine politics of the 2016 Presidential race

I’ve been writing about vaccines and the antivaccine movement since the turn of the millennium, first in discussion forums on Usenet, then, beginning in 2004, on my first blog (a.k.a. the still existing not-so-super-secret other blog), and finally right here on Science-Based Medicine (SBM) since 2008. Vaccines are one of the most important, if not the most important, topics on a blog...

The Federal Trade Commission takes on homeopathy—maybe

Well, I’m back. OK, returning from London isn’t nearly as epic as Sam Gamgee’s final words in The Lord of the Rings returning to his wife and daughter after having accompanied Frodo, Gandalf, Bilbo, and key elves of Middle-Earth to the Grey Havens, there to say goodbye to them as they boarded a ship to the undying lands. I just love the...

“Precision medicine”: Hope, hype, or both?

I am fortunate to have become a physician in a time of great scientific progress. Back when I was in college and medical school, the thought that we would one day be able to sequence the human genome (and now sequence hundreds of cancer genomes), to measure the expression of every gene in the genome simultaneously on a single “gene chip,” and...

Vaccine Whistleblower: An antivaccine “exposé” full of sound and fury, signifying nothing

Life’s but a walking shadow, a poor player That struts and frets his hour upon the stage And then is heard no more: it is a tale Told by an idiot, full of sound and fury, Signifying nothing. – Shakespeare’s Macbeth, Act 5, Scene 5   I don’t review books that often. The reason is simple. My posts for this blog sometimes...

An example of ductal carcinoma in situ.

How should we treat DCIS?

I’ve written more times than I can remember about the phenomenon of overdiagnosis and the phenomenon that is linked at the hip with it, overtreatment. Overdiagnosis is a problem that arises when large populations of asymptomatic, apparently healthy people are screened for a disease or a condition, the idea being that catching the disease at an earlier stage in its progression will...

“Aborted fetal tissue” and vaccines: Combining pseudoscience and religion to demonize vaccines

As hard as it is to believe after seven and a half years of existence and nearly 2,400 posts on SBM, every so often, something reminds me that we here at SBM haven’t discussed a topic that should be discussed. So it was a couple of weeks ago, when I saw a familiar name in a news story that wasn’t about vaccines....

The Woo Boat, or: How far Andrew Wakefield has fallen

File this one under the category: You can’t make stuff like this up. (At least, I can’t.) Let’s say you’re a diehard all-conspiracy conspiracy theorist and alternative medicine believer (a not uncommon combination). You love Alex Jones and Mike Adams and agree with their rants that there is a New World Order trying to suppress your rights. You strongly believe that vaccines...

The 21st Century Cures Act: The (Somewhat) Good, The (Mostly) Bad, and The (Very) Ugly

The approval of new drugs and medical devices is a process fraught with scientific, political, and ethical landmines. Inherent in any such process is an unavoidable conflict between rigorous science and safety on the one side, which tend to slow the process down by requiring large randomized clinical trials that can take years, versus forces that demand faster approval. For example, patients...

Medical marijuana for autism? Where's the evidence?

Medical marijuana as the new herbalism, part 4: Cannabis for autism

When I first started writing about the claims made for medical marijuana and the cannabis oil derived from it, it didn’t take long for me to characterize medical claims for cannabis as the “new herbalism,” as opposed to pharmacognosy, the branch of pharmacology devoted to the study of natural products. The reason is simple. Although I support legalization of marijuana for recreational...
