New to this site recommended by friend . Breast cancer finished RT in Dec but question about CEA tests

[Nycfriend113]

Hi.. my new oncologist (previous one left the hospital I’m followed) ordered a CEA, CA 125 and 15-3. I never had a baseline so MD said difficult to interpret.

Ca 125 and 15-3 within normal limits but CEA slightly elevated (upper limit is 5.0, mine was 5.2). Md had me repeat it in 1 month. Now 5.7. Md doesn’t think means anything and asked to repeat in Nov.

Any similar experiences? Thank you
