Hi @mary4elpo, I can imagine that gettting mixed result of a clear colonoscopy with rising CEA levels is concerning. I moved your question to this existing discussion:
- Had colon cancer and now CEA is rising: Scared https://connect.mayoclinic.org/discussion/colon-cancer-10-year-and-now-raised-cea/

I recommend clicking the link and reading the posts from the beginning. You'll also be able to connect with other members like @segerfan @lisag03 @amariewilkinson @ruchibsq and others.

CEA levels alone are not enough to detect cancer. Has your oncologist scheduled additional testing?
