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...
Prostate Cancer Dilemmas: To Test or Not to Test, To Cut or Not to Cut
Diagnosing prostate cancer based on the prostate-specific antigen (PSA) test is a tricky proposition. The cancer itself can be slow-growing, and the treatment harmful. Medicine is complicated, particularly when it comes to cancer screening.
The mammography wars heat up again
PRELUDE: THE PROBLEM WITH SCREENING If there’s one aspect of science-based medicine (SBM) that makes it hard, particularly for practitioners, it’s SBM’s continual requirement that we adjust what we do based on new information from science and clinical trials. It’s not easy for patients, either. To lay people, SBM’s greatest strength, its continual improvement and evolution as new evidence becomes available, can...
The cancer screening kerfuffle erupts again: “Rethinking” screening for breast and prostate cancer
I see that the kerfuffle over screening for cancer has erupted again to the point where it’s found its way out of the rarified air of specialty journals to general medical journals and hence into the mainstream press. Over the last couple of weeks, articles have appeared in newspapers such as the New York Times and Chicago Tribune, radio networks like NPR,...
Are one in three breast cancers really overdiagnosed and overtreated?
Screening for disease is a real pain. I was reminded of this by the publication of a study in BMJ the very day of the Science-Based Medicine Conference a week and a half ago. Unfortunately, between The Amaz!ng Meeting and other activities, I was too busy to give this study the attention it deserved last Monday. Given the media coverage of the...
PSA – To Screen or Not to Screen
Is the prostate specific antigen (PSA) test worth taking? It's, like, really complicated.
Ultrasound Screening: Misleading the Public
There is a new industry offering preventive health screening services direct to the public. A few years ago it was common to see ads for whole body CT scan screening at free-standing CT centers. That fad sort of faded away after numerous organizations pointed out that there was considerable radiation involved and the dangers outweighed any potential benefits. Now what I most commonly...
