Talk to your doctor : Ask your doctor if this CEA level is significant for you. Smoking can cause an elevated CEA. Your doctor may want to re-evaluate. Try not to worry. It may not be significant. Have you considered stopping your smoking? This would be a first step in reducing your cancer risk. Your doctor may offer you some options to help you quit smoking. Best wishes for a good outcome!

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.
