How is a computed tomography (CT) scan used to diagnose stomach cancer?

ANSWER

A computed tomography (CT) scan can give your doctor detailed pictures of structures inside of the body using X-rays. This test is used after a stomach cancer is diagnosed in order to determine the stage of the cancer. To evaluate whether the tumor has spread to the lymph nodes or other organs, the chest, abdomen, and pelvis are scanned. The CT scan can also detect fluid in the abdomen (ascites) as well as abdominal and pelvic nodules.
