What is the CA19.9?
CA 19.9 is a cancer antigen that exists on the surface of cancer-causing cells. The levels of CA 19.9 are elevated highly during pancreatic cancer. CA 19.9 can be measured in the blood. Testing of the levels of CA 19.9 is useful as a tumor marker. The CA 19.9 level elevates especially during pancreatic cancer. The levels of CA 19.9 can, however, be elevated in the conditions of other cancers like Ovarian cancer, lung cancer, liver cancer, cholangiocarcinoma(gallbladder and bile duct cancers), gastric cancers, etc.
What is the CA 19.9 test?
The CA 19.9 test helps in assessing and monitoring the levels of CA 19.9 in the blood. The CA 19-9 test is used as a tumour marker in cancerous conditions. In some cases, your health practitioner might also suggest CA 19.9 test in other body fluids like urine, semen, CSF etc.
Why did my doctor recommend me to undergo the CA 19.9 test?
There are various conditions that your doctor might want to diagnose via the CA 19.9 test. Some of the conditions under which your doctor has recommended you to take the CA 19.9 test are discussed here.
– The CA 19.9 test is used as a tumor marker. Hence your doctor might suggest the test to ensure if there is any cancerous growth.
– To diagnose if there is any new cancerous growth in the pancreas.
– The recurrence of the pancreas cancer can also be detected by the CA 19.9 test.
– The CA 19.9 test is also suggested in order to evaluate the response of a person to the treatment of pancreatic cancer.
Your health practitioner can suggest you the Ca 19.9 test also to differentiate between pancreatic cancer and other conditions.
When should I undergo the CA 19.9 test?
There are a few symptoms related to the abnormal levels of the CA 19.9. When you are experiencing such symptoms consecutively or recurrently, you should definitely undergo the Ca 19.9 test. Some of the most common symptoms are listed below:
– Abdominal pain or gastritis
– Back pain
– Nausea and anxiety
– A sudden shift in appetite
– Abrupt weight loss
