Description:
A protein made
          by the body that stimulates the growth of many types of
          cells. Insulin-like growth factor is similar to
          insulin (a hormone made in the pancreas). There are two
          forms of insulin-like growth factor called IGF-1 and
          IGF-2. Higher than normal levels of IGF-1 may increase the
          risk of several types of cancer.
          Insulin-like growth factor is a type of growth
          factor and a type of cytokine. Also called IGF and somatomedin.
