Abstract :
The mortality rate of the patients with gastric cancer is reduced dramatically from past few years. Still the gastric cancer the major concern that is in front of health care professionals and is the second leading cause of cancer death across the world. But the trend of infection and the severity of infection differ as per location and histology. While there has been a marked decline in distal, intestinal type gastric cancers, the incidence of proximal, diffuse gastric carcinoma has been increasing, particularly in the Western countries. The severities of gastric cancer infection also differ by change in geographical location, social and economic status of the respective race as well. The main risk factors for distal gastric cancer include Helicobacter pylori infection and dietary factors; whereas gastro esophageal reflux disease and obesity play important roles in the development of proximal stomach cancer. The main aim of this review is to determine the epidemiology of gastric cancer and to discuss about available strategies for its prevention.
