Professional Interests:

Dr. Welch is a general internist at the White River Junction VA and a professor of Medicine at the Dartmouth Institute for Health Policy and Clinical Research.

For the past two decades, Dr. Welch’s research has focused on the problems created by medicine's efforts to detect disease early: physicians test too often, treat too aggressively and tell too many people that they are sick. Much of his work has focused on overdiagnosis in cancer screening: in particular, screening for melanoma, thyroid, lung, breast and prostate cancer. His first book, SHOULD I BE TESTED FOR CANCER? Maybe not and here's why (UC Press 2004) was written while he was a Visiting Scientist at the International Agency for Research on Cancer and was one of the six "best books" listed by Malcolm Gladwell in The Week. He has recently published his second book, OVERDIAGNOSED: Making people sick in the pursuit of health (Beacon Press 2011).
