Question: I had colon cancer surgery in March 2016. There were 12 out of 37 lymph nodes that showed cancer following surgery. I elected to have immunotherapy as an alternative to chemotherapy. My CEA after immunotherapy at the end of May was 3.5. On July 1st my CEA was 3.7. I just had the CEA takend last Friday, August 5th and it was 4.0. Does this mean that the cancer has returned or is somewhere else in my body?

Brief Answer:
Serially increasing CEA levels indicate recurrence consult your oncosurgeon

Detailed Answer:

Thank you for posting your health query here.

The CEA levels that are increasing over time after immunotherapy indicate a recurrence of the cancer. It could be in the same area or it could be at a different site. This can be best identified with the help of a PET scan. Kindly consult with your treating oncosurgeon and follow her/his advice.

Wishing you good health and good luck.

Warm regards.
