Cea blood test levels low but cat scans show more cancer?

Possible: Please note that cea is just another tool we have and as such it is not perfect.

I'm 33 - smoker - family history of cancer - Had blood test all normal but CEA 5.4 - creatinine 0.6 - monocytes 9% . Could I have cancer?

Why were you tested?: CEA is a poor screening test in people without symptoms or signs of cancer. And reference ranges are set so that a few percent of healthy folks fall outside on either end. This is very slightly above reference range and not uncommon for a smoker. Please try to stop and ask your physician whether chest imaging and/or colonoscopy are in order. ...Read more
