Gastric Cancer

Screening and Tests for Gastric Cancer

Diagnosing gastric cancer begins with a physical exam and laboratory tests. These tests include a fecal occult blood test, which detects microscopic blood in the stool that may indicate stomach or other gastrointestinal cancers; a complete blood count, which is a simple blood test that measures the concentration of white blood cells, red blood cells and platelets in the blood; tumor marker test, which looks for the presence of biomarkers that may indicate cancer; genetic testing, which is used to screen high-risk individuals and confirm cancer in suspected cases by looking for mutations of specific genes; upper GI series, or barium swallow, in which the patients drinks a thick, chalky liquid that coats the esophagus and stomach and makes it easier to detect abnormalities on x-rays; upper endoscopy, in which an endoscope is inserted through the mouth and into the stomach to enable doctors to retrieve a small sample of a suspected tissue for biopsy; and imaging tests, such as CT scans, ultrasounds, MRIs and PET scans.
