Pap Technology

Women have been going to their gynecologists for Pap tests for more than 50 years. And their vigilance has paid off: Mortality rates from cervical cancer have dropped 70%, according to the American College of Obstetricians and Gynecologists. But a woman's chance of getting a false negative -- a result that says she's healthy when she really has cancer or pre-cancerous cells -- is still between 10 and 25%, according to the ACOG.
