Colonoscopy
Colonoscopia
What it means
Colonoscopy is an examination of the inside of the colon using a colonoscope inserted into the rectum. The National Cancer Institute dictionary describes a colonoscope as a thin, tube-like instrument with a light and a lens for viewing, which may also have a tool to remove tissue to be checked under a microscope for signs of disease. MedlinePlus says the procedure is most often done by a specially trained doctor called a gastroenterologist. Reasons it may be done include screening for colorectal cancer, blood in the stool, changes in bowel movements, inflammatory bowel disease, and follow-up of a past finding such as polyps or colon cancer. Polyps, small growths on the lining of the colon, can be removed through the colonoscope during the exam. In Spanish the term is colonoscopia.
