As of 2015, information on the normal range for cancer markers is available at OncoLink.org, states Penn Medicine. The website chart shows markers that medical professionals use most frequently, cancers with which the markers can be present, noncancerous marker-elevating conditions, and the normal results range.


Most tumor markers are made by normal cells as well as by cancer cells; however, they are produced at much higher levels in cancerous conditions. These substances can be found in the blood, urine, stool, tumor tissue, or other tissues or bodily fluids of some patients with cancer. Most tumor markers are proteins.


Guide to Tumor Markers Used in Cancer. This is a table of the most often used tumor markers, the cancers they can be found with, non-cancerous health issues that can cause them to be elevated, and the range of normal results. In cases where the half-life is listed, this should be kept in mind when checking levels.


Tumor markers are substances found at higher than normal levels in the blood, urine, or body tissue of some people with cancer. Although cancer cells often produce tumor markers, healthy cells in the body may produce them as well. Tumor markers are also called biomarkers.Tumor markers and cancerHigh tumor marker levels can be a sign of cancer.


Tumor Markers Key Information. For baseline and observation — to assess tumor burden and monitor levels of tumor and indicate a recurrence; prognosis (what treatment to use if the tumor should recur); most tumor markers are NOT specific, meaning that positive result does not necessarily mean that the primary site can be readily identified.


CEA levels, together with other tumor markers are used for staging the cancer. It can assist in planning the treatment of the cancer. Biggest role for CEA tumor marker in colon cancer is monitoring the treatment. CEA levels return to normal within 4-6 weeks after surgical resection of the tumor.


My brother was just diagnosed with testicular cancer, so I'm trying to learn everything I can about the disease. Most of it makes sense, but there's a steep learning curve when it comes to understanding lab reports. What exactly is a "normal" tumor marker number for testicular cancer?


Not all doctors use cancer markers. They're not known to be extremely accurate. Mine uses them for trend information only. To tell you the truth, I'm not sure how I feel about them. My number is normal now, so it gives me some reassurance. However, if it starts to rise, I know I will freak out even if it's still in the normal range.


Read about CA 125, a test used to determine levels of a tumor marker that may be elevated in cases of ovarian cancer. Certain benign conditions, including endometriosis, uterine fibroids, and pelvic inflammatory disease, may be associated with increased CA 125 results. Learn about normal values for CA 125.


I have not been in normal range since mets were duagnosed, so I dont get too excited. When I was first diagnosed in 2002, my tumor markers were normal. The first time the CA125 was elevated was with mets in 2010. Best of luck to you, and CCthanks for the information, I didnt even know what tumor markers were until I came to this board.
