In an age when a significant part of world population is fighting battles against different types of cancer, gastric cancer still has no screening tests available for its diagnosis, which makes it dangerous and lethal. Recently, many advances have been made to develop new regime schemes. This book highlights the evaluation of premalignant lesions, current management of early gastric cancer, risk and protective factors in gastric carcinogenesis. An elaborated description on morphologic classification, molecular changes and epigenetic alterations of this tumor has also been provided in this book. It provides a descriptive account of various diagnostic tools in the pre-operative analysis of patients and the pivotal aspects resulting in the prognosis. Furthermore, it provides insight into the recent operative and chemotherapeutic choices for gastric neoplasm. This text can be used as a pathway to future discoveries relating to carcinogenesis, genetic and epigenetic alterations, signaling pathways, H. pylori infections, the researches of defensive elements against gastric cancer and of profound treatments of this tumor.
