A colonoscopy is considered the gold standard for colon cancer screening because not only can the entire colon be visualized, but polyps can be removed if they are found. Follow-up after these types of polyps are found is also important to allow for early detection and removal of any new polyps that might occur. Two key factors may explain the occurrence of postcolonoscopy (ie, interval) cancers in the proximal colon, namely endoscopist-dependent factors and biological characteristics of precursor lesions resulting in a more rapid progression. This book explores the past, present, and future of colorectal cancer genetics, with particular emphasis on how knowledge of the molecular pathogenesis of the disease leads to the development of novel therapeutic strategies.
