CEA: Is a blood test. This is a test to monitor response to colon cancer treatment (is not used for screening or diagnosis- this is very important to understand). Persistet elevation after treatment signals residual disease or reocurrence. A low value does not rule out reocurrence. Smoker tend to have elevated results. Your oncologist will monitor this and follow proper oncolgy guidelines for colon ca.

CEA. : CEA. Is not used as a screening test. Only to follow a malignancy along pre/post-treatment. Its is not only for colon cancer. Many other cancers will cause its elevation. Also it is important to realize that there are other causes for CEA elevation that are not rooted in cancer.
