However many people feel embarrassed or afraid when faced with the procedure. During a colonoscopy, a specialist doctor examines the lining of your colon for any abnormal tissue growths called polyps. If left untreated could invite potentially cancerous situations.

The colonoscope is a flexible plastic tube equipped with a small digital camera and light at one end, which is used during the colonoscopy procedure. It is an effective method for detecting colon polyps or bowel cancer, as well as aiding in the diagnosis of symptoms like unexplained diarrhoea, abdominal pain, or blood in the stool. Additionally, it allows for the removal of early cancers and polyps during the same procedure.

Though colon cancer may not produce visible symptoms in its early stages, routine colonoscopy screenings can detect and remove polyps before they become cancerous. A colonoscopy allows a specialist to carefully guide a camera-equipped instrument through the colon to closely inspect its lining for any signs of cancer or precancerous growth. This minimally invasive procedure provides a magnified view of the colon via a monitor, helping doctors find and remove dangerous polyps even when there are no outward symptoms.

Early-stage colorectal cancer typically does not show symptoms, which is why colonoscopies play such a vital role. By using colonoscopies to examine the colon and rectum where cancer begins, doctors can detect and treat cancerous and precancerous cells early. Following colorectal cancer screening guidelines and getting recommended colonoscopies saves lives by finding colorectal cancer in its earliest, most treatable stages. Colonoscopies are also used as a diagnostic tool when people have concerning symptoms.

A colonoscopy can detect a variety of conditions, including cancer as well as other issues like diverticulosis, diverticulitis, intestinal infections, and inflammatory bowel disease!
