There was a thread about CEA marker some time ago. I am one of those whose CEA level was not elevated even at diagnosis. Although I do still have CEA test done periodically, I am pretty skeptical about its value for me. My oncologist is doing another marker test for me, called "CA 19.9". He told me that, among individuals who have a recurrence AND whose CEA is not elevated, about 50% have an elevated CA 19.9. He says it is "not in the textbooks" (yet). I should probably state that I am not a doctor, I haven't read up on this myself, and I'm not trying to push this test -- but just wanted to share this information with you -- in case anyone is intersted in exploring.
