My boyfriend has been battling Colon Cancer for a year and a half now. Recently his Doctor did some blood tests and called us with the results. He said the results were 18 and "explained" that 0-5 was normal so the fact that his was 18 caused concern. What are they measuring and what does that mean?
They were most likely referring to the level of CEA, a colorectal cancer tumor marker, in his blood. Unfortunately, a rising CEA level following treatment for colon cancer usually indicates a recurrence of the patient's cancer.
He should be seen by his Oncologist, and a search for the source of this rising CEA level. Hopefully, he can receive additional treatment.
