Colonoscopy Q & A

What is a colonoscopy?

A colonoscopy is a same-day procedure that uses a long, flexible scope to look inside your colon (your large intestine) so Dr. Sherman can check for signs of colon cancer or other bowel diseases and evaluate and remove small growths called polyps. Performed under sedation, colonoscopy uses a colonoscope with a tiny camera on the end to transmit pictures of your colon to a computer screen for viewing. The colonoscope can also be used to remove fleshy growths called polyps and other tissue samples for evaluation under a microscope.

What steps do I have to take to prepare for my colonoscopy?

The day before your colonoscopy, you'll need to take a preparation either in liquid or pill form to clean your bowels so the bowel walls can be clearly seen during the procedure. The preparation will cause you to move your bowels frequently. You'll also be given instructions about what medications you can and can't take, and your diet will be restricted.

How often should I have a colonoscopy performed?

Guidelines recommend most people should have a colonoscopy every five years beginning at age 50; however, if you have a personal or family history of colon cancer or if you have other risk factors that increase your risk for developing colon cancer, you will need more frequent screenings.

What happens if Dr. Sherman finds a polyp?

First, don't worry: Many polyps are benign (not cancerous). When a polyp is found during a colonoscopy, it can be removed at the same time without the need for an additional procedure. The polyp tissue will be sent to a lab for evaluation to determine if any cancerous cells are present. If cancerous tissue is found, Dr. Sherman will discuss your treatment options that might be needed to prevent cancer from developing.
