What is a Polyp?
A polyp is a lesion that protrudes from the surface of the bowel. There are many different kinds of lesions that can be called polyps. These range from benign to malignant.
Often, the term is used to refer to pre-cancerous lesions. We currently understand that bowel cancers may develop through a series of steps. A polyp phase is thought to happen before the bowel cancer becomes invasive. So, if polyps can be removed, this might prevent the development of bowel cancer.
