Colonoscopy: The Gold Standard for Colorectal Cancer Detection

Published: Jul 16, 2024

Colonoscopy is the most effective tool for detecting and preventing colorectal cancer. This powerful screening test allows doctors to examine the entire colon and remove precancerous growths.

What Happens During a Colonoscopy?

During a colonoscopy, a long, flexible tube with a tiny camera is inserted through the rectum to examine the entire colon. The procedure typically takes 30-60 minutes and is done under sedation for comfort. The doctor can see the lining of the colon in detail, looking for any abnormal growths or areas of concern. If polyps are found, they can often be removed during the same procedure.

Preparing for the Procedure

Proper preparation is crucial for a successful colonoscopy. This involves clearing the colon completely so the doctor can see the entire lining clearly. Patients follow a special diet for 1-2 days before the procedure and drink a strong laxative solution to empty the bowels. While the prep can be uncomfortable, it's essential for an accurate exam.
