Dr. Gil Welch has written a book called "Over-Diagnosed: Making People Sick in the Pursuit of Health."
Welch feels American overscreens for too many conditions -- and iti s resulting in treating people for illnesses that would never cause them problems.
"For twenty years I've been concerned about how we look hard at the well to see if we could prevent illness. One of the questions I ask doctors is, is looking hard at the well, good for the healthcare system and I'm not sure it is. I think we have to be careful about looking too hard for things to be wrong."
Dr. Welch specifically points to mammograms for breast cancer and PSA tests for prostate cancer as tests that are overused by doctors.
He feels Big Pharma and medical product manufacturers have financial incentives to push these screenings and doctors concerned about malpractice order the tests to protect themselves.
