β-HCG as a Tumor Biomarker with Special Reference to Breast Cancer | Human chorionic gonadotropin (HCG) is a placental protein hormone initially secreted by cells (syncitiotrophoblasts) from the implanting conceptus. It supports the ovarian corpus luteum, endometrial lining and consequently maintains pregnancy [1]. The hormone can be detected in blood and urine, as it is the basis of many pregnancy tests. HCG plays many other roles including stimulating the onset of fetal gonadal steroidogenesis, promotion production of corpus luteal progesterone, immuno-suppression and blockage of phagocytosis of invading trophoblast cells, cytotrophoblast differentiation, growth and differentiation of fetal organs [2]. It is well known that a biomarker is any molecular and chemical changes that can be measured and used to study normal or abnormal process in the body. A tumor marker, like a biomarker, is a naturally occurring substance in the body. A tumor marker can be made by cancer cells or by the body in response to cancer. Tumor markers can provide information that can be used to screen and diagnose cancer as well as identify the stage of cancer to monitor a treatment.
