Two Studies Recommend Less-Frequent Colon Exams

Two new large medical studies recommend less frequent and less invasive colon exams for most people over 50.

Colon exams are recommended for everyone over 50 to prevent colon cancer, the second biggest cancer killer in the U.S., with some 52,000 deaths last year. Doctors use the exams to find, and if necessary remove, harmless growths before they become cancerous, but the screening process can be expensive and unpleasant.
