How is colorectal cancer diagnosed?
Colonoscopy
. A colonoscopy is an invasive exam and uncomfortable.
. It is used to detect changes or abnormalities in the large intestine(colon) and rectum.
. During a colonoscopy, a long flexible tube (colonoscope) is inserted into the rectum. A tiny video camera at the tip of the tube allows the doctor to view the inside of the entire colon.
. If necessary, polyps or others types of abnormal tissue (biopsies) can be removed through the scope during a colonoscopy.
Fecal occult blood test (FIT)
. FIT is a stool test designed to identify possible signs of bowel disease.
. It detects minute amounts of blood in feces (fecal occult blood).
. If there is blood in the stool this can indicate the presence of abnormalities in the bowel.
. Patients with a positive FIT result are referred for further investigation by colonoscopy.
