'Experts' Say Doctors Over-testing, Over-treating

Too much cancer screening, too many heart tests, too many cesarean sections. A spate of recent reports suggest that too many Americans - maybe even President Barack Obama - are being overtreated.

Is it doctors practicing defensive medicine? Or are patients so accustomed to a culture of medical technology that they insist on extensive tests and treatments?

A combination of both is at work, but now new evidence and guidelines are recommending a step back and more thorough doctor-patient conversations about risks and benefits.

As a medical journal editorial said this week about Obama's recent checkup, Americans including the commander in chief need to realize that "more care is not necessarily better care."
