Polyps are commonly found in the colon, stomach, nose, ear, sinus(es), urinary bladder, and uterus. They may also occur elsewhere in the body where mucous membranes exist like the cervix, vocal folds, and small intestine. Some polyps are tumours (neoplasms) and others are nonneoplastic (for example, hyperplastic or dysplastic).
Types
The following types of polyps occur in the human body:

- Hyperplastic polyps: These are usually benign and not likely to become cancerous.
- Inflammatory polyps: These often occur after an injury or inflammation.
- Hamartomatous polyps: These are usually benign and are associated with certain syndromes when they occur in children.
- Serrated polyps: These can become cancerous if not removed.
