Likely to be: Cea or carcinoembryonic antigen, is a tumor marker usually associated with colon cancer, but can be seen elevated in other tumors. When associated with colon cancer, it is useful to follow serially after resection or to follow as part of treatment. If the value is normal at one point and becomes elevated, then a careful search for recurrence is indicated.
