Furthermore, mucosal inflammation, even if subtle, is the single most common pathway for GI cancer. This book discusses all aspects of the relation between inflammation and GI cancer, from the basic science through to the translational science which is helping in the optimization of clinical management strategies. Among the topics considered are the impact of inherited syndromes; the roles of acid reflux, H. pylori, inflammatory bowel disease, and primary sclerosing cholangitis; screening strategies;
