H. Gilbert Welch, M.D., M.P.H.

Dr. Welch is Professor of Medicine and Community and Family Medicine at The Dartmouth Institute for Health Policy & Clinical Practice. He is also Co-director of the VA Outcomes Group.

A general internist, Dr. Welch's research focuses 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. Most of his work has focused on overdiagnosis in cancer screening: in particular, screening for melanoma, cervical, breast and prostate cancer.

He is the author of two books, "Should I be Tested for Cancer? Maybe Not and Here's Why" (UC Press 2004) and more recently, "Overdiagnosed: Making People Sick in the Pursuit of Health" (Beacon Press 2011).
