There are often no symptoms with stomach cancer, but when they occur, they may include:

  • Indigestion, heartburn
  • Abdominal pain or vague abdominal discomfort
  • Nausea and vomiting
  • Diarrhea or constipation
  • Stomach bloating or sense of fullness after eating
  • Loss of appetite
  • Weakness, fatigue
  • Bleeding in vomit or stool
  • Stool that has turned black or tarry
  • Unintended weight loss
  • Fluid swelling in abdomen

These symptoms may also be caused by other, less serious health conditions. A person experiencing these symptoms should see their doctor to determine the cause of the problem.


Your doctor will ask about your symptoms and medical history, and perform a physical exam.

Diagnostic tests may include:

  • Blood tests
  • Fecal occult blood test —This test checks for blood in the stool.
  • Upper GI series —X-rays are taken after a barium solution is swallowed.
  • Endoscopy—The stomach is viewed through a thin, lighted tube that is passed through the mouth and into the stomach.
  • Biopsy —Tissue is removed for testing during endoscopy.
  • Ultrasound
  • CT scan
