Tests and diagnosis
By Mayo Clinic staffTests and procedures used to diagnose esophageal cancer include:
- Using a scope to examine your esophagus (endoscopy). During endoscopy, your doctor passes a hollow tube equipped with a lens (endoscope) down your throat and into your esophagus. Using the endoscope, your doctor examines your esophagus looking for cancer or areas of irritation.
- X-rays of your esophagus. Sometimes called a barium swallow, an upper gastrointestinal series or an esophagram, this series of X-rays is used to examine your esophagus. During the test, you drink a thick liquid (barium) that temporarily coats the lining of your esophagus so that the lining shows up clearly on the X-rays.
- Collecting a sample of tissue for testing (biopsy). A special scope passed down your throat into your esophagus (endoscopy) or down your windpipe and into your lungs (bronchoscopy) can be used to collect a sample of suspicious tissue (biopsy). What type of biopsy procedure you undergo depends on your situation. The tissue sample is sent to a laboratory to look for cancer cells.
Esophageal cancer staging
When you're diagnosed with esophageal cancer, your doctor works to determine the extent (stage) of the cancer. Your cancer's stage helps determine your treatment options. Tests used in staging esophageal cancer include computerized tomography (CT) and positron emission tomography (PET), among others.
The stages of esophageal cancer are:
- Stage I. This cancer occurs only in the top layer of cells lining your esophagus.
- Stage II. At this stage, the cancer has invaded deeper layers of your esophagus lining and may have spread to nearby lymph nodes.
- Stage III. The cancer has spread to the deepest layers of the wall of your esophagus and to nearby tissues or lymph nodes.
- Stage IV. At this stage, the cancer has spread to other parts of your body.
