I am 5 years out of a colon resection, stage 2 only because of size.  No lymph node involvemnent. Have all regular check  ups, etc  Did radiation and chemo  as precaution.  My cea levels are like a yoyo.  nothing over 5.0, but seem to go up and down with any inflammation in my body. Doctors have me do ct scans, etc.  Is this too abnormal?
Hi and welcome to Chat Doctor thanks for the query. It fluctuates even without inflammation processes in our body so this shunt concern you as long as there is no significant grow. Wish you good health. Regards
