polyp
Let an agent explain polyps and their kinds in general terms from clinical sources, describe screening and removal for colon polyps, distinguish benign from precancerous types, and route personal questions to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain polyps and their kinds in general terms from clinical sources, describe screening and removal for colon polyps, distinguish benign from precancerous types, and route personal questions to clinicians.
An abnormal growth of tissue projecting from a mucous membrane, attached by a stalk or a broad base, occurring in the colon and intestine, stomach, nose, uterus, cervix, bladder, vocal cords and rarely the heart, and classified as hyperplastic, inflammatory, adenomatous or other types; most polyps are benign but adenomatous colon polyps can progress to cancer, which is why screening colonoscopy removes them, and polyps elsewhere may cause bleeding, obstruction or voice change.
What it is for: Not applicable; a growth type.
It can be explain kinds and sites; relay screening and removal; distinguish benign from precancerous; route personal questions.
Distinguishing features
Mucosal projection
Stalked or sessile
Many sites
Precancerous potential in some
What it looks like
A rounded or stalked growth on a mucous surface, seen at endoscopy.
Physical character
adults over 50 with colon polyps: about 25-30 percent - estimates
adenoma to cancer progression: about 10 years - typical
How it is recognised
Growth projecting from a mucous membrane
Intestinal, uterine, nasal, bladder, vocal cord and cardiac polyps; hyperplastic and adenomatous types
Papillomas are epithelial frond-like tumours; cysts are fluid-filled; polyps in cnidarians are animals

- The registry entry has merged aliases naming site-specific polyps; should they be split off?
