A colonoscopy is a procedure where your doctor can closely check the lining of the entire colon (large bowel). During a colonoscopy, your doctor inserts a tube through your rectum into your colon. A camera attached to the tube allows your doctor to view the inside of your colon and check for abnormailities. Polyps can be removed and biopsies taken to rule out cancer.
A colonoscopy is a procedure that uses a device called a colonoscope to look at the inside of your rectum and colon. (The colon (large intestine) is the last part of the digestive system. It’s a hollow tube, 4 to 6 feet long, starting at the small intestine and ending at the rectum.) The colonoscope is a long, flexible tube with a tiny video camera at the end. The camera sends images to a monitor, allowing your doctor to see a variety of problems.
Colonoscopy is the best test for detecting pre-cancerous polyps and cancer. The doctor can often remove polyps, perform biopsies, and treat problems during theprocedure itself.
This is a test where a flexible tube the diameter of large pencil is inserted into the rectum, and the entire colon is examined through this telescope. It involves cleaning out the colon the day before to allow for a good view of the entire colon.
Colonoscopy is a diagnostic procedure that allows the physician to examine the entire length of the large intestine. Colonoscopy can assist in identifying problems with the colon, such as early signs of cancer, inflamed tissue, ulcers, and bleeding. Colonoscopy is also used to screen for colorectal cancer, the second leading cause of cancer deaths in the US.
An endoscope—a long, flexible, lighted tube (also called a colonoscope)—is inserted through the rectum into the colon. In addition to allowing visualization of the internal colon, the colonoscope enables the physician to irrigate, suction, inject air, and access the bowel with surgical instruments. During a colonoscopy, the physician may remove tissue for further examination and possibly treat any problems that are discovered.
A colonoscopy may be used to examine colon polyps, tumors, ulceration, inflammation, diverticula (pouches), strictures (narrowing), and foreign objects within the colon. It may also be used to determine the cause of unexplained chronic diarrhea or gastrointestinal bleeding or to evaluate the colon after cancer treatment.
Colonoscopy may be indicated when the results of a barium enema and/or sigmoidoscopy warrant further examination of the colon.
A colonoscope is a thin, tube-like instrument used to examine the inside of the colon. A colonoscope has a light and a lens for viewing and may have a tool to remove tissue.

A colonoscopy is a procedure that allows the physician to view the entire length of the large intestine, and can often help identify abnormal growths (polyps), inflamed tissue, ulcers, and bleeding. It involves inserting a colonoscope -- a thin, flexible tube with a light and camera at the end—through the rectum up into the colon. The colonoscope allows the physician to see the lining of the colon, remove tissue for further examination, and possibly treat some problems that are discovered. Patients are sedated during this procedure, which typically takes 20-30 minutes. Preparation for a colonoscopy may include a liquid diet several days prior to the procedure, a laxative the night before, and an enema the day of the procedure.
A colonoscopy is a routine exam to diagnose rectal cancer and colon cancer. During a colonoscopy, your doctor inserts a tube through your rectum and into your colon. A camera attached to the tube allows your doctor to view the inside of your colon and check for abnormalities. Polyps and early stages of cancer can be removed during a colonoscopy.
Colonoscopy is considered the “gold standard” screening for colon cancer and also enables doctors to remove any suspicious growths or tissue during the procedure. Colonoscopy is generally recommended every 10 years.
