These symptoms can also indicate conditions other than stomach cancer. If you are experiencing any of these symptoms, contact your doctor as soon as possible.
Diagnosing Stomach Cancer
One or more of the following tests may be used to diagnose stomach cancer.
- Upper endoscopy uses a thin, flexible, lighted tube inserted into the mouth and guided down the throat to allow your doctor to view your stomach and remove a tissue sample for biopsy, if needed. An ultrasound device on the tip of the scope may be used to obtain images of the stomach and determine if the cancer has spread.
- A biopsy involves the removal of a sample of stomach tissue to be examined under the microscope for the presence of cancer. The sample is usually obtained during an upper endoscopy procedure.
- An upper gastrointestinal (GI) series (also called a barium swallow) consists of X-rays of the upper digestive system (the esophagus, stomach and first section of the small intestine) with use of barium, an imaging agent, to outline any abnormal areas.
- A fecal occult blood test examines a small sample of stool for the presence of blood, which may indicate cancer.
