E A.C.

It is a glycoprotein secreted primarily by tumors of gastrointestinal origin.
This dose in the blood.
The elevation of the CEA (carcino embryonic antigen) can occur in colorectal bleeding, Crohn's disease, intestinal polyps, some gastritis, liver disease, particularly alcoholic (cirrhosis).
Beyond 50 nanograms per liter, it is often a sign of a malignant disease.
After a colon or gastric cancer, its normalization is a good prognosis and monitoring to quickly detect recurrence.
Normal value: below 5 nanograms per liter.
The MARKERS are substances that help to affirm a disease from a biological point of view. In particular, currently, many markers and thus can be assayed to determine the existence, or rather the evolution of a cancerous tumor. The degree of specificity of these markers is variable, that is to say, some are very specific markers of specific tumors: for example, the determination of P S A... (Prostate Specific Antigen) is specific for prostate cancer.
C antigens. A. (Carbohydrate antigens) are very many specific tumors.
- For example, the C A.. 19/9 is a marker of pancreatic tumors of the stomach, bile duct, colon.
- The C A.. 50 is a marker for tumors of the gastrointestinal tract, ovary, and uterus.
- The C A.. 15/3 is a marker for tumors of the breast, ovary and lung.
- The C A.. 125 is a marker for ovarian cancer, endometrium (lining of the uterus), cervix, pancreas.
- It should be noted that the determination of these markers can be used to detect cancerous tumors, but can follow the development of these tumors after treatment, whether surgical or chemotherapy.
- For the record, the A C is not very specific but very useful in monitoring certain digestive or glandular tumors E (carcinoembryonic antigen)....

Alpha-fetoprotein is also useful in monitoring liver cancer.
