Areas of Expertise
Dr. Welch is a general internist whose 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 the 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).
