A polyp is a protrusion on the surface of the colon's epithelial lining. Colon polyps can be pedunculated or have broad legs. Histologically, colonic polyps can arise from either the epithelial layer (adenoma, hyperplastic polyp) or the stromal layer (hamartoma).

Familial colon polyps are classified as a rare genetic disease in clinical practice. This inherited type of polyp causes colon polyps, affects several organ functions in the body and needs to be treated as soon as possible to prevent them from developing into cancer.
