The term '''cancer''' refers to many different diseases.  They all have in common uncontrolled ''cell proliferation'' (growth and division).  Cancers are usually named for the organ or cell type that is originally involved. After beginning at one site, cancer may ''metastasize'' (spread) to other organs.  The cancer is still named by its place or origin.
