癌胚抗原 CEA
Carcinoembryonic Antigen (CEA)
*Carcinoembryonic antigen (CEA) is a protein produced during fetal development, and its levels are typically low in the blood of adults. Elevated CEA levels are commonly associated with certain types of cancer, particularly gastrointestinal cancers like colon and rectal cancer.
*Normal Range
Adult normal range: ≦5 ng/mL
*Risks Associated with Elevated CEA Levels
-Colon and Rectal Cancer:
CEA is a common tumor marker for colon and rectal cancers. Elevated levels are often associated with the presence of these cancers.
-Other Cancers:
CEA levels may also increase in other cancers such as pancreatic cancer, breast cancer, gastric cancer, and lung cancer.
-Benign Conditions:
Elevated CEA levels can sometimes be seen in benign conditions such as liver diseases, lung diseases, inflammation, or smoking.
*Health Recommendations
-Further Investigation:
If CEA levels are elevated, further testing is needed to determine whether cancer or another health issue is present. This may include imaging studies or biopsies.
-Monitoring Cancer Progression:
For patients with known cancers, CEA testing can be used to monitor treatment effectiveness and assess the risk of cancer recurrence.
*Conclusion
CEA is a useful tumor marker for diagnosing and monitoring certain cancers, but it can also be influenced by non-cancerous factors. It should be used in conjunction with other diagnostic tests to accurately assess a person's health status.
