Today's CEA and the Suspected Plan

My CEA today is 2.1, still trending upwards. I see the doctor on Monday for my every-other-week Avastin infusion. He was planning on doing this infusion and then two more before repeating my PET scan but I suspect that since it's been going up since the last scan, and that it's now above 2.0, the scan will be after this infusion. I expect the next PET scan will be done around April 5th, give or take a day.
