It starts from one of the cell types found in the lining of the stomach.Adenocarcinoma is a common cancer of the digestive tract. It is less common in the stomach in the United States, compared to Asia. It is diagnosed much more often in people in eastern Asia, parts of South America, and eastern and central Europe. It occurs most often in men over age 40.The number of people in the United States who develop this cancer has decreased over the years. Experts think this decrease may be in part because people are eating less salted, cured, and smoked foods.You are more likely to be diagnosed with gastric cancer if you: Have a diet low in fruits and vegetables Have a family history of gastric cancer Have an infection of the stomach by a bacteria called Helicobacter pylori ( H pylori) H pyloriHelicobacter pylori (H pylori) is a type of bacteria that infects the stomach.
