How is stomach cancer diagnosed?
If a doctor believes your symptoms require further investigation, they may ask about your medical and family history and perform a physical examination.
Blood tests can be used to look for anemia, and stool testing may check for hidden blood.

One of the main diagnostic procedures is an upper endoscopy.
During an endoscopy, a doctor uses a thin flexible instrument with a camera to examine the esophagus, stomach and the first part of the small intestine.
If an abnormal area is found, a biopsy can be taken.
A biopsy allows specialists to examine tissue under a microscope and determine whether cancer cells are present.

Additional imaging and tests may be needed if cancer is diagnosed, particularly to determine whether it has spread and to help doctors plan treatment.
