Colonoscopy is a procedure to screen for and potentially treat colorectal cancer. During the procedure, a flexible colonoscope is inserted through the rectum into the colon to allow the physician to view the entire length of the large intestine.

Using guided imagery, the physician is able to examine the lining of the colon through the scope. At the same time, tissue can be removed for further examination. The physician may even treat problems discovered during the procedure.

Colonoscopy is usually performed by a gastroenterologist, a physician who specializes in gastrointestinal conditions and diseases. Inova Fairfax Hospital Advanced Endoscopy Center is the first of its kind in Northern Virginia to offer the most innovative endoscopic technologies available to successfully treat both cancerous and non-cancerous diseases of the digestive tract – conditions that once required traditional surgery.
