The colon and rectum are the two main parts of the large intestine.

Colonoscopy is a procedure used to see inside the colon and rectum. Colonoscopy can detect inflamed tissue, ulcers, abnormal growths. The procedure is used to look for early signs of colorectal cancer and can help doctors diagnose unexplained changes in bowel habits, abdominal pain, bleeding from the anus and weight loss.


What are the colon and rectum?

The colon and rectum are the two main parts of the large intestine. Although the colon is only one part of the large intestine, because most of the large intestine consists of colon,the two terms are often used interchangeably. The large intestine is also sometimes called the large bowel.

Digestive waste enters the colon from the small intestine as a semisolid. As waste moves toward the anus, the colon removes moisture and forms stool. The rectum is about

6 inches long and connects the colon to the anus. Stool leaves

the body through the anus. Muscle and nerves in the rectum

and anus control bowel movement.


At what age should routine colonoscopy begin?

Routine colonoscopy to look for early signs of cancer should begin
at age 50 for most people - earlier if there is a family history of

colorectal cancer, personal history of inflammatory bowel disease,

or other risk factors. Dr. Andres will advise patients about how

often to get a colonoscopy.
