Anylink between tumor markers and covid vaccine?

Assuming that your tumor markers (Ca27.29, Ca15-3) have always been correlated with imaging, after covid vaccine, does anyone experience rise in tumor markers WITHOUT correlation with increase in size of tumor from imaging?

    I am sorry that you haven’t gotten a reply, Nguyen. I have not had tumour markers run in about four years so I can’t really help directly, but I think your question is interesting and perhaps a response might help get your thread some attention.

    Not exactly answering your question, but twice I’ve had my CA 15-3 checked about 4 weeks after vaccination with Moderna. My TMs did not increase even though I had a severe rash from the first one (likely due to a combination of meds and existing rash).
