Carcinoembryonic Antigen (CEA)

Carcinoembryonic Antigen (CEA)

Why It Is Done

The carcinoembryonic antigen (CEA) test is used to:

  • Find how widespread cancer is for some types of the disease, especially colon cancer.
  • Check the success of treatment for colon cancer.
    • CEA levels may be measured both before and after surgery to evaluate both the success of the surgery and the person's chances of recovery.
    • CEA levels may be measured during treatment with medicines to destroy cancer cells (chemotherapy). This provides information about how well the treatment is working.
  • Check to see if cancer has returned after treatment.
