Insulin-like growth factor is a hormone involved in controlling the production of growth hormone (somatotropin). This growth factor is synthesized starting from the period of intrauterine development and throughout life. The peak of IGF-2 production occurs during the period of embryogenesis (development of the fetus before birth). After birth, the production of IGF-2 does not stop, but remains at a low level. It can increase due to some oncological pathologies. First of all, with a tumor of the cortex of the adrenal glands. Therefore, the analysis for insulin-like growth factor II is used as a marker for this type of cancer.
