Tumor markers are substances found in the blood, urine or body tissues that can be elevated in cancer. There are many different tumor markers. They are used in oncology to help determine the presence of cancer. An elevated level of a tumor marker can indicate cancer, however there can often also be other causes of the elevation.
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 can be used in screening programs, such as screening for elevated levels of prostate specific antigen (PSA) to indicate possible prostate cancer. Tumor markers are also used to monitor patients for cancer return. Tumor markers can be classified in two groups: Cancer-specific markers and tissue-specific markers.
