Mammography and overdiagnosis, revisited
Another new study supports the hypothesis that overdiagnosis is a major problem in mammography screening programs. Predictably, it is attacked based on a misunderstanding of what overdiagnosis is.
Reclassifying thyroid cancer and the willful misunderstanding of overdiagnosis
If there’s one lesson that we here at Science-Based Medicine like to emphasize, it’s that practicing medicine and surgery is complicated. Part of the reason that it’s complicated is that for many diseases our understanding is incomplete, meaning that physicians have to apply existing science to their treatment as well as they can. The biology of cancer, in particular, can be vexing....
Confusing overdiagnosis for an “epidemic” of thyroid cancer in Japan after Fukushima
One of my favorite topics to blog about for SBM is the topic of overdiagnosis and overtreatment. These are two interrelated phenomena that most people are blissfully unaware of. Unfortunately, I’d also say that the majority of physicians are only marginally more aware than the public about these confounders of screening programs, if even that. Overdiagnosis has long been appreciated to be...
“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...
Overdiagnosis
Dr. H. Gilbert Welch has written a new book Over-diagnosed: Making People Sick in the Pursuit of Health, with co-authors Lisa Schwartz and Steven Woloshin. It identifies a serious problem, debunks medical misconceptions and contains words of wisdom. We are healthier, but we are increasingly being told we are sick. We are labeled with diagnoses that may not mean anything to our health....
COVID-19 antivax quacks are now “repurposing” ivermectin for cancer
A year ago, I noticed that COVID-19 quacks were touting the "repurposing" of ivermectin to treat cancer. Now, familiar COVID-19 antivaxxers—cough, cough, FLCCC—have turbocharged this quackery.
The People Can Decide the Best Policy, Only If They Have the Best Information
Doctors who prioritized politics over being a "neutral judge" failed to provide the best information.
The return of marketing hype for “whole body scans”…now with AI!
Two decades ago, I cut my skeptical teeth countering advertising for whole body scans by companies making extravagant promises for their products. This particular medical fad faded for a while, but now it's back with a vengeance...with AI! Looking at these products, what I see is basically the quackery that is functional medicine on steroids and powered by AI.
A Perhaps Not-So-Unexpected Spike in Pediatric Brain Abscesses
The surge in viral infections last year appears to be to blame for a significant increase in cases of brain abscesses in children. They remain rare, and panic is not warranted, but they are a life-threatening complication of common bacterial infections that should be taken seriously.
Autism prevalence increases to 1 in 38, and antivaxxers blame vaccines without using the word “vaccine”
The CDC updated its estimates for the prevalence of autism spectrum disorders. Predictably, antivaxxers blame the increasing prevalence of ASDs reported, particularly in Black children, on "environmental factors," which is antivax code for, "Vaccines are to blame."
