My dad is stage IV colon cancer (diagnosed May 2002). In the past a rising CEA level for him correlated to a spot or two on his liver (cancerous). In February, his CEA was 2.8 and he had radiofrequency ablation done on the one liver spot. Since then, his CEA has been rising. Now it is 9. Back in April when his CEA was 6, he had a clean PET scan. Our oncologist does not seem too concerned at this time. He mentioned that my dad's CEA level was in the safe range. My concern is the lack of consistency. Even at a 2.8, we could see a spot on the PET scan. Now a 6 does not even register. He is on the folfox treatment every other week. The oncologist metioned that the CEA could also be caused by irritation. Any thoughts out there or similar experiences?
