Stomach Cancer Stage

Assays
Assays are tests that measure the levels of beta-human chorionic gonadotropin, CA-125, and carcinoembryonic antigen (CEA) in the blood. These substances are released into the bloodstream from both cancer cells and normal cells. When these substances are found in higher-than-normal amounts, they can be a sign of stomach cancer or other conditions.
 
Chest X-ray
A chest x-ray is an x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.
 
Endoscopic Ultrasound (EUS)
An endoscopic ultrasound is a procedure in which an endoscope (a thin, lighted tube) is inserted into the body. The endoscope is used to bounce high-energy sound waves (ultrasound) off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. This procedure is also called endosonography.
 
Computed Tomography (CT) Scan
A CT scan is a procedure that takes a series of detailed pictures of areas inside the body from different angles. A computer linked to an x-ray machine creates these pictures. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computerized tomography or computerized axial tomography (CAT).
 
Laparoscopy
A laparoscopy is a surgical procedure that is used to examine the organs inside the abdomen to check for signs of disease. Small incisions are made in the wall of the abdomen, and a laparoscope (a thin, lighted tube) is inserted into one of the incisions. Other instruments may be inserted through the same or other incisions to perform procedures such as removing organs or taking tissue samples for biopsy.
