The Importance of Colonoscopy

Most people with colon cancer have no symptoms, so it is important to have a regularly scheduled screening colonoscopy to ensure your health.

Colorectal cancer is preventable, and potentially curable, when detected in the early stages. Even with the ability to prevent and cure colorectal cancer, it is still the second most common cause of cancer death in the United States.

What is a Colonoscopy?

A colonoscopy is an outpatient procedure in which the inside of the large intestine (colon and rectum) is examined. A colonoscopy is commonly used to evaluate gastrointestinal symptoms, such as rectal and intestinal bleeding, abdominal pain, or changes in bowel habits. Colonoscopies are also performed in individuals without symptoms to check for colorectal polyps or cancer. A screening colonoscopy is recommended for anyone 50 years of age and older, and for anyone with parents, siblings or children with a history of colorectal cancer or polyps.


Flexible Sigmoidoscopy

What is a flexible sigmoidoscopy?
Flexible sigmoidoscopy is an examination of the inside of the rectum and the lower part of the colon. This is done in our office.  A flexible sigmoidoscope is a lighted tube that is inserted into the rectum and advanced into the colon, allowing the doctor to examine the lining of the lower 60cm of the colon.

Why should I have flexible sigmoidoscopy?
Flexible sigmoidoscopy is performed to evaluate symptoms, such as rectal bleeding, abdominal pain, diarrhea, or change in bowel habit.  It is also used to detect colon polyps or colon cancer. Most colon cancer begins in polyps (benign growths in the lining of the colon). Studies show that up to 70% of all polyps occur in the lower portion of the colon. If polyps are detected, they are removed in a later procedure.  Flexible sigmoidoscopies are usually done as an office procedure.
