Stomach Cancer Stage

PET Scan (Positron Emission Tomography Scan)
A PET scan is a procedure that is used to find malignant tumor cells in the body. A small amount of radionuclide glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do.

In stage II stomach cancer, the cancer has spread:
 
  • Completely through the mucosal (innermost) layer of the stomach wall and is found in 7 to 15 lymph nodes near the tumor
OR
  • The cancer has spread to the muscularis (middle) layer of the stomach wall and is found in up to six lymph nodes near the tumor
