tumor marker detection

The tumor marker (TumorMarker) is a chemical substance that reflects the presence of a tumor. They may not be found in normal adult tissues but only in embryonic tissues, or in tumor tissues in a much larger amount than in normal tissues. Their presence or quantitative change may indicate the nature of the tumor, thereby understanding the tumor tissue formation and cell differentiation. , cell function to help diagnose, classify, prognose and treat treatment of tumors.
