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 elevated level of a tumor marker. Tumor markers can be produced directly by the tumor or by non-tumor cells as a response to the presence of a tumor.
