Stomach (Gastric) Cancer Prevention (PDQ®): Prevention - Patient Information [NCI] - General Information About Stomach Cancer

Stomach (gastric) cancer is a disease in which malignant (cancer) cells form in the stomach.

The stomach is a J-shaped organ in the upper abdomen. It is part of the digestive system, which processes nutrients (vitamins, minerals, carbohydrates, fats, proteins, and water) in foods that are eaten and helps pass waste material out of the body. Food moves from the throat to the stomach through a hollow, muscular tube called the esophagus. After leaving the stomach, partly-digested food passes into the small intestine and then into the large intestine.
