What kind of tests do I need to take to test to check for stomach cancer?

Endoscopy. There are no blood tests etc, that can be used to check for stomach cancer. In the us, the only test that can check for stomach cancer is an upper endoscopy. In this procedure, a thin scope is placed down the mouth and into the stomach. A gastroenterologist then closely examines the entire stomach and biopsies any suspicious areas.
Egd. And egd is the most important test as it looks with a camera at the lining of the stomach and a biopsy can be done. Other test would be done if cancer was found.
