Understanding Carcino Embryonic Antigen in Secunderabad

What is Carcino Embryonic Antigen in Secunderabad?

A carcinoembryonic antigen (CEA) test is a blood test used to diagnose and manage certain types of cancers. The CEA test is used especially for cancers of the large intestine and rectum. CEA is a type of tumor marker which is found in the body. The CEA test is done to monitor cancer treatment. It acts as an indicator of the size of the present tumor and also helps to assist in cancer staging.

In addition to colon and rectal cancer, CEA testing may be done for the following types of cancers like breast, lungs, thyroid, and pancreatic cancer. CEA testing is not used for screening cancer in those who have no symptoms. It is also not used for cancer diagnosis because other noncancerous conditions can cause CEA levels to increase and not all cancers cause CEA levels to rise.

Frequently Asked Questions about Carcino Embryonic Antigen in Secunderabad

Q. How is the blood sample taken?

The healthcare provider takes a blood sample from the arm. The site from where the blood is to be withdrawn is cleaned with a swab of rubbing alcohol. This is then followed by inserting a small needle which has a tube attached to it for collecting blood. Once the sufficient blood for analysis is withdrawn, the needle is removed. The site is then covered with a gauze pad.

Q. Is there any risk associated with the withdrawal of blood sample procedure?

As such there is no risk but in few cases, bruising, bleeding, and infection at the puncture site can be seen. In very few cases, there can be swelling of the vein after the blood is withdrawn.

Q. What does the CEA test result mean?

The implications of test results include monitoring of cancer treatment. Initially elevated levels of CEA when get decreased after surgery indicate that the cancer has been successfully treated. A steadily rising CEA level is often the first sign of tumor recurrence. For staging - On initial testing, people with smaller and early-stage tumors are likely to have a normal or only slightly elevated CEA levels. People with larger tumors (tumor burden), later-stage cancer, or tumors that have spread throughout the body are more likely to have increased CEA levels. For testing of metastasis - Presence of CEA in body fluid other than blood results in increased growth of cancer.

Q. What are the drawbacks of CEA test?

CEA is not a very effective screening test for hidden (occult) cancer since early tumors may not cause significant blood elevations. Also, there are cases where many tumors never cause an abnormal blood level, even in advanced disease.
