FAQs
A tumor marker that may be used for monitoring certain cancers, especially colorectal, when clinically indicated.
No. It is not recommended for routine cancer screening in healthy individuals.
Usually no.
Yes, smokers can have higher baseline CEA; disclose smoking status for interpretation.
No. CEA is not diagnostic and can rise in benign conditions; clinicians interpret with imaging and history.
To monitor trends and treatment response over time.
Often same day or within 24 hours.
Serum blood sample.
Yes in many serviceable areas.
Inflammation, liver disease, and other non-cancer conditions may affect levels; clinician interpretation is required.
Commonly colorectal; other uses depend on tumor type and clinician plan.
Discuss with your clinician; trends and context matter.

No. Treatment decisions rely on the full clinical picture and imaging.

CEA levels may be elevated in smokers and benign disease.
