The incidence of gastric cancer is decreasing and lies between 10 and 15 new cases per 100,000 population per year in most Western countries. Peak age is between 60 and 80 years. While distal gastric cancers account for the overall decrease in gastric cancer, tumors in the proximal stomach (cardia and esophagogastric junction) are on the rise. Recognized risk factors for gastric cancer are infection with Helicobacter pylori, dietary factors (e.g. high intake of salt-preserved foods), smoking, pernicious anemia and a history of partial gastrectomy.
在大多数西方国家，胃癌的发病率正在下降，每年每 10 万人中有 10 到 15 例新发病例。发病高峰年龄在 60 至 80 岁之间。虽然远端胃癌导致胃癌总体减少，但近端胃（贲门和食管胃交界部）的肿瘤正在增加。胃癌的公认危险因素包括感染幽门螺杆菌、饮食因素（例如高盐腌制食品摄入）、吸烟、恶性贫血和部分胃切除术史。
