Cancer Marker Profile (Stomach) Monoclonal Antibody Blood
What is this test?
Cancer marker profile (Stomach) Monoclonal Antibody Blood is used to detect whether an individual is having stomach cancer or not.
What are Stomach and Stomach cancer?
The stomach is a muscular organ that is located on the left side of the upper abdomen. It receives food and secretes the enzymes and acid that digests the food. Stomach cancer is also known as gastric cancer in which the cells in the lining of the stomach grows uncontrollably and cause severe problems like inflammation of the lining of the stomach, vomiting, pain in abdomen and stomach.
What is CEA, CA 19-9, and CA 72-4?
A tumor marker is a substance produced by the body in the presence of cancer or cancer itself can make tumor markers. Some of the tumor markers are specific to one cancer and some are seen in different types of cancers.
Carcinoembryonic antigen CEA is a protein generally produced in the gastrointestinal tissue during fetal development. But, its production is stopped before the birth of a child. So, CEA levels in the blood of healthy adults are very low. The Carcinoembryonic Antigen CEA can be used as tumor markers for stomach, pancreatic, lung, gastric and breast cancers.CEA attaches to the plasma membrane of tumor cells and gets released into the blood.
Carbohydrate antigen 19-9 CA 19-9 is a type of antigen released by the pancreatic cancer cells. It can be used to differentiate cancer and other diseases of the glands.
Cancer Antigen 72-4 CA 72-4 is a type of antigen release by the recurrent tumours of the lung, breast, ovaries and gastrointestinal tract.
