You Are "Pre-Diseased", Part 1 & 2 (Listen)

Why wait until you are diagnosed with cancer, if you can hunt it down before it could kill you? Why not get a simple high tech CT scan to see if you are harbouring signs of pre-disease in your heart, your lungs, your breasts or your bowels? Those are the questions that dog Health Researcher Alan Cassels as he voyages inside the world of cancer screening, taking him from his own doctor's office to the world's biggest medical meeting. Part 2 airs Wednesday, January 13.

Program Excerpt:


Alan Cassels: I have this ad in my hand: A Body Scan Can Save Your Life. For a reality check, I talk to Dr. Gilbert Welch, who works at Dartmouth Medical School in Vermont and is currently on sabbatical in Montana. He's working on a new, as yet untitled, book that seems to me like the next chapter to the book of his I'm holding in my hands called: Should I Be Tested for Cancer, Maybe Not and Here's Why. He is a little cagey about the substance of the book-in-progress, but he tells me that it's about overdiagnosis: the fact that the way medicine is practised, we get far too many diagnoses of disease without substantive improvements in patient care. He uses an analogy that captures the gestalt of our time in a world where, it seems, more and more overdiagnosis is becoming the norm, where everyone is, more or less, prediseased.

Dr. Gilbert Welch: I think the generic problem is somewhat like the "check engine" lights on your car. Do you have check engines lights? My first car was a '75 Ford Fairlane. There were only two things monitored: my oil pressure and my engine temperature. I now drive a Volvo that is 10 years old, but it is checking about 25 different engine functions. And sometimes a check engine light comes on, and you're really glad to know, and it leads to something you want to do something about. Sometimes the check engine light is just a nuisance, and it just keeps flashing on and off and the mechanic can't fix it. And some of the audience might have this experience where they went to get it fixed and it made matters worse. And if you had that experience, you've had some of the experience of overdiagnsosis and that's what I'm worried about. We're putting more and more check engines lights on the human body. We have to ask ourselves if that is really the best way to get to a healthy society. We're constantly monitoring for things to be wrong. Is that really the best way to achieve health?
