    Signs and tests

    Diagnosis is often delayed because symptoms may not occur in the early stages of the disease. Or, patients may self-treat symptoms that gastric cancer has in common with other, less serious gastrointestinal disorders (bloating, gas, heartburn, and a sense of fullness).

    The following tests can help diagnose gastric cancer:

    • Complete blood count (CBC) to check for anemia
    • Esophagogastroduodenoscopy (EGD) with biopsy
    • Stool test to check for blood in the stools
    • Upper GI series
