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...
The American Cancer Society’s new mammography guidelines: Déjà vu all over again
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 the same issues come up again and...
“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...
The uncertainty surrounding mammography continues
Mammography is a topic that, as a breast surgeon, I can’t get away from. It’s a tool that those of us who treat breast cancer patients have used for over 30 years to detect breast cancer earlier in asymptomatic women and thus decrease their risk of dying of breast cancer through early intervention. We have always known, however, that mammography is an...
In which Dr. Gorski is taken to task by an eminent radiologist for his posts on mammography
Introduction: An unexpected e-mail arrives One of the consequences of the growing traffic and prominence of this blog over the last few years is that people who would otherwise have probably ignored what I or my partners in blogging write now sometimes actually take notice. Nearly a decade ago, long before I joined this blog as a founding blogger, if I wrote...
Mammography and the acute discomfort of change
As I write this, I am attending the 2014 meeting of the American Association for Cancer Research (AACR, Twitter hashtag #AACR14) in San Diego. Basically, it’s one of the largest meetings of basic and translational cancer researchers in the world. I try to go every year, and pretty much have succeeded since around 1998 or 1999. As an “old-timer” who’s attended at...
The Canadian National Breast Screening Study ignites a new round in the mammography wars
The last couple of weeks, I’ve made allusions to the “Bat Signal” (or, as I called it, the “Cancer Signal,” although that’s a horrible name and I need to think of a better one). Basically, when the Bat Cancer Signal goes up (hey, I like that one better, but do bats get cancer?), it means that a study or story has hit...
A holiday round in the mammography debate
There are times when the best-laid blogging plans of mice and men often go awry, and this isn’t always a bad thing. As the day on which so many Americans indulge in mass consumption of tryptophan-laden meat in order to give thanks approached, I had tentatively planned on doing an update on Stanislaw Burzynski, given that he appears to have slithered away...
