The colonoscope is a long, flexible tube equipped with a camera and light, allowing healthcare providers to examine the interior lining of the colon for abnormalities, lesions, polyps, or signs of disease such as colorectal cancer. During this procedure, also known as a colonoscopy, the physician can not only visualize but also perform therapeutic interventions, such as biopsy or polypectomy, if necessary.
