A polyp is a non-cancerous growth found on mucous membranes, including those found in the digestive tract, nose, mouth, uterus, bladder, and genitals. They are termed benign, or noncancerous, but over time can become cancerous if left untreated. Like many forms of cancer, polyps are often discovered during routine screenings. For colon polyps, that includes colonoscopies. Polyps of the colon have two defined shapes, pedunculated and sessile and are classified by type; some common and others rare.
Otherwise known as lymphoid hyperplasia, this is a benign growth, generally found in the presence of clusters of lymphoid follicles in the colon or rectum. Detected on a lymphoid by radiographic x-rays are small polypoid lesions, either localized or generalized. When symptoms like bleeding, pain, bowel movement changes, and intussusception arise, diagnosis is made through a biopsy, and removal is typically performed to eliminate any chance of the polyps being mistaken for malignant forms.
