This book describes the historical context of colorectal cancer predisposition syndromes and the latest knowledge relating to each of the known hereditary colorectal cancer predisposition syndromes. There is a particular focus on the management of each of these syndromes in turn, including medical and surgical management, cancer surveillance, and screening recommendations. It also explores the workings of specialised hereditary and familial cancer clinics from the perspectives of the various clinicians involved in the running of the service. Multidisciplinary management, universal tumour screening, risk estimation, the obtaining and use of genetic information, and appropriate high-risk population screening and surveillance are also discussed, as are future developments and how these may relate to this exciting and evolving field.
