Both benign and malignant (harmless and cancerous) conditions can increase the CEA level. The most frequent cancer which causes an increased CEA is cancer of the colon and rectum. Others include cancers of the pancreas, stomach, breast, lung, and certain types of thyroid and ovarian cancer. Benign conditions which can elevate CEA include smoking, infections, inflammatory bowel disease, pancreatitis, cirrhosis of the liver, and some benign tumors in the same organs in which an elevated CEA indicates cancer. Chemotherapy and radiation therapy can cause a temporary rise in CEA due to the death of tumor cells and release of CEA into the blood stream. Benign disease does not usually cause an increase above 10 ng/ml.
Thanks to Karen and Anna for the articles. I am just finished with treatment 5 of 12 on Xeloda and oxaliplatin and my CEA is of the steadily rising sort so far. The one article said a spike and then a drop was better than steadily rising. Guess I can hope that it will be lower next time, but it is worrying me.

Hi k1,
I hope this helps.
What conditions can cause an elevated CEA?

An interesting study out of England that may give some hope.
