Irene, I don't have any experience with Avastin, but your comment on how your counts differ on the CEA and CA 27-29 caught my eye.
I've never had the CEA done, as the CA 27-29 seems to work very well for me.
Have the values of the two always differed, or is the CA 27-29 just slower to react to changes in your mets?
