You say that your doctors have advised you not to worry that your GI symtoms (symptoms) are related to cancer, so I assume you are under regular medical care.

The two tests you had done are considered "nonspecific" when it comes to screening for cancer, although they have some value for patients already known to have cancer, and in measuring response to treatment.

Noncancerous conditions that may elevate CA 19-9 levels include gallstones, pancreatitis, cirrhosis of the liver, and cholecystitis.
Not all cancers produce CEA, and a positive CEA test is not always due to cancer. Therefore, CEA is not used for screening the general population.

Therefore, the tests values you obtained by themselves do NOT mean
that you have colon cancer. (I think some of the nervousness you mentioned may sometimes make you jump to the worst possible conclusions about your health, right?)  Just report any new and unusual symptoms to your doctors and follow whatever screening procedures they recommend.

And if you are so anxious and worried that it makes it difficult to enjoy life, you might want to consider seeing a mental health therapist.

Best wishes...
