    What is the function of Cancer Marker CEA screening?
    CEA major rule in clinic practice:
    1.    Assess the effectiveness of surgery or other treatment, such as the condition is stable or may relapse.
    2.    Assess the possibility of cancer metastasis.
    It should be conservative while using CEA as a screening purposes. Because a single increase in CEA does not necessarily represent the occurrence of cancer, several continuous raised are more clinical significance. Similarly, normal CEA result cannot completely rule out the possibility of cancer.
