How We Diagnose Stomach Cancer
City of Hope diagnostic tests may include:
 
  • Physical exam and history
  • Gastroscopy: A thin, lighted tube called a gastroscope is inserted through the mouth and guided into the stomach. A local anesthetic or other medicine may be given to minimize discomfort.
  • Barium swallow/Upper GI series: A series of X-rays is taken after the patient drinks a liquid to improve the visualization of the inside of the upper gastrointestinal tract.
  • Biopsy: If tests indicate that stomach tissue seems abnormal, a small sample may be taken for examination under a microscope to check for cancer cells.
