Hi there.
Thank you for your question.
I will be helping you out with your queries.
In the first few weeks of chemotherapy CEA can rise and this actually indicates that you are responding to chemotherapy.
Here are two links to support what I am saying:

Ok thx .so after round 1 it jumped to 80 and was 65 before chemo .if after round 2 it goes to 55, would you count the drop from the original 65 or the 80?

Expert:  Dr. SH replied 2 years ago.
Yes I would count that as a drop and that you are responding to chemotherapy.
