What are the stages of esophageal cancer?

ANSWER

The stages of esophageal cancer are given a number (I through IV); the higher the number, the more advanced the cancer.

  • Stage 0: Abnormal cells (not yet cancer) are found only in the layer of cells that line the esophagus.
  • Stage I: Cancer cells are found only in the layer of cells that line the esophagus.
  • Stage II: Cancer has reached the muscle layer or the outer wall of the esophagus. It may have spread to 1 to 2 nearby lymph nodes.
  • Stage III: Cancer has reached deeper into the inner muscle layer or the connective tissue wall. It may have spread into surrounding organs or more lymph nodes nearby.
  • Stage IV: Cancer has spread to other organs in the body or far lymph nodes.
