If CEA (Carcinoembryonic Antigen) Serum Test results are present (elevated), it may indicate various conditions, including colorectal cancer or other cancers such as lung, breast, or pancreatic cancer. Further evaluation, including imaging studies and possibly tissue biopsies, may be necessary to determine the underlying cause.
If CEA Serum Test results are absent (within normal range), it suggests that CEA levels are not elevated. However, it does not rule out the possibility of cancer, as not all cases of cancer result in elevated CEA levels. Additional diagnostic tests and evaluations may be needed, especially if there are other concerning symptoms or clinical findings.
