CEA Marker numbers

HalThompson

Colon cancer moved into the liver.  Treated and was cancer free for two years while taking Avastin treatments.  Last scan revealed recurrence in liver.  My lab numbers, especially my CEA; cancer marker number and all other numbers reveal little or no change.  Is this possible? If cancer returned wouldn’t numbers have changed? Any thoughts or others experienced the same?

My understanding is CEA is for specific cancers, not for liver. If your Colon cancer has met to liver, you may want to test the tumor marker (AFP) for the liver.
