Has anyone heard of a rising CEA being related to necrosis of a tumor? I have a tumor in the liver. The tumor is shrinking (per PET/CT Scan) but the "SUV" (standard Uptake Value) has risen from 7.3 to 9.3 and the CEA rose from 18 to 24 in less than 6weeks! I'm on Fulfori too. Could the shrinking tumor be related to the elevation? I don't think so...but someone asked me to consider such. What's your take? Thanks for info in advance!
