For both diagnostic and therapeutic purposes, cancer markers are being monitored to get an idea about the status of the disease. However, most individual cancer markers are not highly specific, because they are not exclusively expressed and secreted by tumour cells. Therefore, instead of the mere presence of one marker, specificity is often obtained by measuring the levels of a combination of different markers or different forms of the same marker.
Alpha-fetoprotein (AFP) is a major plasma protein produced by the fetus. AFP is measured in pregnancy as a screening test for a subset of developmental abnormalities. It is also used as a biomarker to detect a subset of tumors.
