Colonoscopy
Colonoscopy is by far the most common and precise technique for colon cancer diagnosis. It is often performed by a gastroenterologist, a doctor specializing in dealing with digestive tract issues. During this procedure, the expert will insert a colonoscope, which is a flexible tube, into the anus. When the camera is moved along the rectum to the colon, your doctor can look around to check for any signs of cancerous cells and growths. There are different types of colonoscopy, including diagnostic, routine screening, and virtual. Each option has its own pros and cons, which can suit different people. [2]
