What Is The Cancer Marker Lab Test Cea Something
Colon cancer marker: The cea (carcinoembryonic antigen) test is a colon cancer tumor marker. As with most tumor markers, it is not used as a screening test for colon cancer (in other words, it is not used to find the cancer because of a relatively high false positive rate) but it is used to monitor the cancer once it has been diagnosed. This is particularly useful for treated colon cancer to see if the tumor reoccurs. ...Read moreSee 2 more doctor answers
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
My ca 15-3 test is 29.04& normal in the lab where i did it is <25 & my CEA is 3.03 normal is <3.8.Is it breast cancer?I have lumps in rt breast
Is a CEA lab result of a 4.4 a good indicator for stage 4 colon cancer that perhaps the cancer has not spread that much? Better survival rate?
No: Cea (carcinoembryonicantigen) is a protein that is released by some tumors into the bloodstream. It is useful for follow-up of cancer after treatment, ie, if the cea is elevated before treatment and returns to normal after treatment, we are optimistic that the cancer was well-treated. If it then becomes elevated, we must search for recurrence. In your case, it is impt to know the # pre-rx. ...Read more
I am a breast cancer survival - do I need to do the tumour markers blood test -ca153, ca19.9, ca12.5, cea, afp?
Generally no: Standards of care in the us do not recommend routine tumor marker testing in cancer survivors (we usually do ca 27.29 for breast cancer). Markers are mostly useful to assess response to therapy in patients with advanced cancer. That said, many oncologists (myself included) will sometimes order routine markers in cancer survivors depending on the circumstances. ...Read moreSee 2 more doctor answers
A friend has been told they have colon cancer, diagnosed via a tumour marker blood test, high cea, CT scan showed contained mass. Is this conclusive?
No, but...: But very suspicious for colon cancer. If your friend is similar in age to yourself a mass in the colon on ct scan is cancer until proven otherwise. And cea levels can go up for other reasons but, given the mass, they would strongly favor cancer. But to answer your question "no"... They are not definitive. You would need a piece of the mass under a microscope to prove definitively its cancer. ...Read moreSee 1 more doctor answer
When a cyst is removed (from back) and it is sent for lab tests, what are the things they are testing for, is it just cancer or other things?
Depending how used: CEA first identified in 1965 by Phil Gold and Samuel O. Freedman in human colon cancer extracts. Thought to be valuable for dx colorectal Ca but the glycoprotein is also expressed in inflamed tissue so that smoking and enema can cause rise. Best used for monitoring so that if present in primary and rises it represents treatment failure and if diminishes during treatment it represents a response. ...Read moreSee 2 more doctor answers
Not completely: If there's a mass, it should be examined by ultrasound. Blood tests can further suggest the likelihood of cancer by finding abnormal amounts of hormones and proteins. Usually entire testicle removed instead of biopsy, because of risk of spreading cancer cells that were previously contained. Exam by pathologist will guide treatment. Ct can evaluate for metastasis. ...Read moreSee 1 more doctor answer
