In brief: Very good question!

The answer's somewhat debated.
1st, CEA levels even in the presence of cancer r somewhat variable, so my 1st question is *how much* did the values rise? An increase of 1 mcg/L may not b significant, though an increase of 100 mcg/L is definitely so. Also, levels increase if u r around cigarette smoke. Lastly, CEA could be released from cancer cells as they die. TTYD (Oncologist) to interpret numbrs
