Yesterday, my latest scan results came out (chest, abdomen and Pelvis)- MRI and PET and they were clean. No evidence of disease. But the CEA had a value of 15.6
My CEA has never been high. Even during diagnosis, it was <0.5. My doctor has added another blood test for CEA this week and if he sees a high, he will order a colonoscopy. I hope I do not have a met in my neck, head or limbs. I feel fine and do not have any symptoms.
Usually my blood is drawn prior to my scans. But this time, it was immediately after the scans during which contrasts were injected. Could that affect CEA? Could covid vaccination affect CEA?
Anyone experienced this yet?
