Don’t Slam Canada for Mammogram Study (CNN)


In an opinion piece on CNN, Dartmouth’s H. Gilbert Welch says medical care is too often more about “professional interests” than about science.

A professor of medicine at The Dartmouth Institute for Health Policy & Clinical Practice, Welch writes about the publication last week of a 25-year follow-up of the Canadian National Breast Screening Study, and subsequent criticism of the new study.

“The headline was simple: Mammogram screenings don’t reduce cancer death rates,” says Welch, the author of Should I Be Tested for Cancer? Maybe Not and Here’s Why.

That the American College of Radiology discredited the study was predictable, he says. “It’s predictable because it is exactly what they did when they didn’t like the first findings of the study published more than 20 years ago,” he writes.
