Colonoscopy is done by passing a flexible tube into the rectum. Then it is manipulated under direct vision, that means the tube is made to negotiate all the curves of the large intestine. That tube is actually a collection of prisms and lenses by which the doctor can see inside the intestine.
It is not done under anaesthesia but a sedation is given to allay your anxiety. It is not painful but it is "irritating".
Any suspicious looking area can be removed and sent for examination.
The main thing is, will it give a diagnosis ?
The answer is, "Only time will tell".
