A carcinoembryonic antigen (CEA) test measures a specific blood glycoprotein called CEA. It means a protein with a lot of sugars added to it by normal or cancerous cells. Scientists first discovered CEA in 1968 when they isolated extracts of liver metastasized by colorectal cancer and also from normal fetal digestive tract.

2021年11月15日 · A CEA test measures the level of carcinoembryonic antigen (CEA) in the blood or other body fluid.

2017年5月13日 · CEA – Carcino Embryonic Antigen is a tumor marker. Tumor markers are substances produced by cell- either normal or cancer cells. Normal cells produce tumor markers in much lower levels as cancer cells. For this reason, elevated levels of …

2024年4月30日 · The Carcinoembryonic Antigen (CEA) blood test is a diagnostic tool used to measure the level of CEA, a protein that can be elevated in certain types of cancer. This test is primarily associated with monitoring colorectal cancer but can also provide insights into other cancers and health conditions.

2021年3月6日 · CEA is the most widely used marker for gastrointestinal cancer. CEA is elevated in colonic cancer and metastatic breast disease. Although the CEA is primarily associated with colorectal cancers, other malignancies that can cause elevated levels of CEA include breast, lung, stomach, pancreas, ovary and other organs.

Carcinoembryonic antigen (CEA) is a significant biomarker widely utilized in oncology. This glycoprotein plays a crucial role in cell adhesion and functions as a marker in various cancers. Recognizing CEA levels can provide invaluable insights in the diagnostic process and treatment management of cancer.

2022年10月29日 · Carcinoembryonic antigen (CEA) is a tumor marker found in the blood or in other bodily fluids that can be used to monitor treatment for certain cancers. This article explains what the CEA test is, when it can be helpful in cancer treatment, and how to interpret its results.
