Tumor marker. A tumor marker is a biomarker found in blood, urine, or body tissues that can be elevated by the presence of one or more types of cancer. There are many different tumor markers, each indicative of a particular disease process, and they are used in oncology to help detect the presence of cancer. An elevated level of a tumor marker can indicate cancer; however, there can also be other causes of the elevation (false positive values). Tumor markers can be produced directly by the tumor or by non-tumor cells as a response to the presence of a tumor.
Tumor markers may also be measured periodically during cancer therapy. A decrease in the level of a tumor marker or a return to the markerâs normal level may indicate that the cancer is responding to treatment, whereas no change or an increase may indicate that the cancer is not responding.here is no âuniversalâ tumor marker that can detect any type of cancer. There are some limitations to the use of tumor markers. Sometimes, noncancerous conditions can cause the levels of certain tumor markers to increase.
