Hi - had routine bloods done 2 weeks ago which showed CEA level 500. No symptoms, no pain, no weight loss, no bleeding, no anaemia. Doctor did physical pelvic examination and couldn’t find or feel anything obvious. Repeated bloods and CEA level has increased slightly. To get bowel screening and ovarian scan. I have had 2 routine National bowel screenings done since I was age 50. Both clear, I am now 54. Doctor doesn’t know what the problem is and didn’t offer any suggestions to put my mind at rest (she’s never been great with communication tbh). I am worried sick at the 500 level as normal readings are around 3. Does this high reading suggest an advanced stage cancer even though I have no symptoms. I am so worried that I can’t sleep.
