Stomach cancer

In medicine, stomach cancer (also called gastric cancer) can develop in any part of the stomach and may spread throughout the stomach and to other organs. The cancer may grow along the stomach wall into the esophagus or small intestine.

Symptoms

Stomach cancer can be hard to find early. Often there are no symptoms in the early stages and, in many cases, the cancer has spread before it is found. When symptoms do occur, they are often so vague that the person ignores them. Stomach cancer can cause the following:

• Indigestion or a burning sensation (heartburn);
• Discomfort or abdominal pain;
• Nausea and vomiting;
• Diarrhea or constipation;
• Bloating of the stomach after meals;
• Loss of appetite;
• Weakness and fatigue; and
• Bleeding (vomiting blood or having blood in the stool).

Any of these symptoms may be caused by cancer or by other, less serious health problems, such as a stomach virus or an ulcer. Only a doctor can tell the cause. People who have any of these symptoms should see their doctor. They may be referred to a gastroenterologist, a doctor who specializes in diagnosing and treating digestive problems. These doctors are sometimes called gastrointestinal (or GI) specialists.
