Colon cancer is one of the most common types of cancer, but if detected early, the chances of recovery are very good. A colonoscopy can not only detect cancer in the early stages, but can also remove precancerous lesions such as polyps before they develop into malignant tumors.

Thorough preparation is essential for a successful colonoscopy. Eat only light meals two days before the examination and begin bowel preparation the day before the examination. You will be given a laxative to completely empty your bowel. It is important to follow your doctor's instructions exactly to create optimal conditions for the examination.

Colonoscopy is performed using an endoscope, a flexible tube with a camera and light source. The doctor carefully inserts the endoscope through the anus into the intestine and examines the intestinal mucosa for abnormalities. Polyps and suspicious tissue samples can be removed immediately. The examination usually takes about 20 to 30 minutes and is performed with the administration of a sleeping medication to increase patient comfort.

Colonoscopy is the most reliable method for early detection of colon cancer. It has the advantage that precancerous lesions can be detected and removed directly. Although the preparation is complex, the examination reduces the risk of dying from colon cancer by up to 90%. The risks include short-term discomfort such as bloating and abdominal pain after the examination. Serious complications are rare but can occur, especially when removing polyps.
