Carcinoembryonic antigen (CEA) levels
암배아항원(CEA) 수준
Carcinoembryonic antigen (CEA) levels vary depending on a number of factors, including smoking status, type of cancer, and stage of cancer:

    • Normal levels

      For healthy, non-smoking adults, CEA levels are usually less than 3 nanograms per milliliter (ng/mL). Smokers may have slightly higher levels, up to 5 ng/mL. 

    • Elevated levels

      CEA levels above 2.9 ng/mL are generally considered abnormal, but they don’t necessarily indicate cancer.

  • Higher likelihood of recurrence

    CEA levels above 10 ng/mL before treatment may indicate a higher likelihood of recurrence and a poor prognosis. 

  • Metastatic disease

    CEA levels above 20 ng/mL are usually associated with metastatic disease in breast and colon cancers. 

  • Response to treatment

    A return to normal CEA levels after treatment usually means that the cancer has responded to treatment. A steadily rising CEA level after treatment often means that the cancer has returned.
