I get CEA tests done every 2 weeks day before treatment with all my other blood tests.
Mine started 2.7 pre-surgery. Then dropped to 1.8/1.9 and then gained back to 2.7/3.8/3.8 and now 4.5
because of the increase for the past 2 months he scheduled a ct scan for me early. I'll get one on the 20th.
I have 2 treatments of 5fu and luecovorin left. Hoping its nothing and the ONC thinks most likely its not cancer, but wants to be proactive in catching anything early.
He also mentioned the first scan may have missed something. It's also possible that your CEA can rise when cancer cells are dying. It can also raise due to inflammation.
I think mine is mostly inflammation related as I'm still having a lot of very loose bowel movements along with mucus. I had a resection prior to chemo - so I don't think my anastomosis is completely healed as well as possible adhesions in the left side small intestines where my colon was removed and placed more center to make the distance up of the lost 8 inches of combined colon/rectum.
So there are multiple factors that can cause small elevation of CEA.
Try not to worry, just get it checked out and move forward.
best of luck.
