What is CEA no... my oncologist never mentioned about my CEA no. going up or down, but couple weeks ago, I had my CT scan done and they suspected that I have scar tissue in my lungs. When I feel my ribcage bone and stomach it hurts.

when I was diagonosed with colon cancer 3 years ago, the symptons were like little fever with my testicles hanging so low... but never noticed that my bloody stool. Later the doctor said, I was anemic. Though my oncologist told me not to fear and I do not have cancer, I couldn't sleep thinking that it might have been back cause of my one symptom. Anyone having same problem and sharing would be appreciated.
