Aspen Ideas Festival: How useful is medical screening?

MPR News - In an interview with Minnesota Public Radio, H. Gilbert Welch, professor of medicine at Geisel, and Dr. Jessica Herzstein of the U.S. Preventive Services Task Force, discuss the pros and cons of medical screening tests and early detection of diseases like cancer. Welch and Herzstein question whether early screening is worth the fear, anxiety, false alarms, and possible over-diagnosis, and say there's not just a dollar cost, but a human cost.
