I don't want to scare you but my CEA gradually went up from .8 to 22. Over a course of six months and the pet scan showed clear, then after six months the pet scan showed something in the pelvic region. My CEA has been a good indicator for me. They put me back on Chemo FOLFIRI and now my CEA is 1.5, but I will have to possibly do surgery next month for curable intent and hopefully once and for all put this thing to bed.
If your CEA has been a good indicator for you most likely your facing a recurrence. I hope not and I hope its a false positive, but seeing the trend on how this works, typically its not a good sign, just being real my friend.
