Answer

The site of stomach cancer is classified on the basis of its relationship to the long axis of the stomach. Approximately 40% of cancers develop in the lower part, 40% in the middle part, and 15% in the upper part; 10% involve more than one part of the organ. Most of the decrease in gastric cancer incidence and mortality in the United States has involved cancer in the lower part of the stomach; the incidence of adenocarcinoma in the cardia has actually shown a gradual increase.
