Smart Patients Get the Best Medical Treatment
That's good advice, says Dr. Mehmet Oz, professor of surgery at Columbia University. Unfortunately, he says, most patients don't educate themselves about their diagnosis or their treatment options.

"Eighty per cent of people never ask for a second opinion, which is a big mistake," he says. "You'd never buy a car without getting a second opinion. The same holds true for getting a diagnosis from your doctor. One third of the time, those diagnoses are changed by what a second doctor may tell you."
