As one of the UK's leading expert in bowel cancer explains, "Most bowel cancers arise from pre-cancerous polypsGrowths on the surface of a mucous membrane (a surface that secretes mucous), lining any body cavity that opens to the outside of the body., and that early detection of these polyps (screeningA way to identify people who may have a certain condition, among a group of people who may or may not seem to) offers the opportunity to prevent bowel cancer developing and to treat the condition before it progresses to an advanced stage."

Mr Austin Obichere at University College Hospital goes on to say, "A smaller proportion of bowel cancers are inherited and a detailed family history by the specialist is required to identify those who may be at risk of the disease."
