Colonoscopy
The most effective tool for colon cancer screening and prevention.
What Is a Colonoscopy?
A colonoscopy is a procedure that allows your doctor to examine the inside of your entire colon (large intestine) using a long, flexible tube called a colonoscope. The colonoscope has a tiny camera and light at its tip, which sends a clear image to a monitor so your physician can carefully inspect the lining of your colon.
Colonoscopy is considered the gold standard for colon cancer screening because it allows your doctor to both detect and remove precancerous polyps in the same procedure. This means a colonoscopy is not just a screening test — it can actually prevent cancer from developing.
Why Would I Need a Colonoscopy?
- Routine screening: The American Cancer Society recommends that adults at average risk begin colon cancer screening at age 45. If you have a family history of colon cancer or polyps, your doctor may recommend starting earlier.
- Blood in the stool: Any unexplained rectal bleeding should be evaluated promptly.
- Changes in bowel habits: Persistent diarrhea, constipation, or narrowing of the stool that lasts more than a few days.
- Unexplained abdominal pain: Ongoing pain that does not have a clear cause.
- Follow-up surveillance: If you have had polyps or colon cancer previously, regular follow-up colonoscopies are important.
- Anemia: Unexplained iron-deficiency anemia may indicate bleeding in the colon.
What to Expect
Before the Procedure
The most important part of your colonoscopy preparation is the bowel prep — a prescribed regimen of laxatives that clears your colon so your doctor can see clearly. Our team will provide detailed instructions and is available to answer any questions. While the prep is often the part patients dread most, modern preparations are much easier to tolerate than in years past.
During the Procedure
You will receive sedation so you will be comfortable and relaxed throughout the procedure. Most patients do not experience any discomfort and have no memory of the exam. The procedure itself typically takes 30 to 60 minutes.
After the Procedure
You will rest in our recovery area until the sedation wears off. You will need someone to drive you home — you cannot drive for the rest of the day. Most patients return to normal activities the following day.
About Polyps
If your doctor finds any polyps during your colonoscopy, they will most often remove them right then and there. This is a routine part of the procedure and does not cause pain. Removed polyps are sent to a lab for examination, and your doctor will follow up with you on the results.
Frequently Asked Questions
Does a colonoscopy hurt?
No. You receive sedation that keeps you comfortable throughout the procedure. Most patients have no memory of the exam at all.
How often do I need a colonoscopy?
For average-risk patients with normal results, every 10 years beginning at age 45. If polyps are found or you have risk factors, your doctor may recommend more frequent screening.
What if I had a colonoscopy years ago — do I need another one?
Yes, if you are due. Screening guidelines are based on your age, prior findings, and family history. Talk to your doctor about when your next screening is recommended.
