Carcinogenesis, also called oncogenesis or tumorigenesis, is the formation of a cancer, whereby normal cells are transformed into cancer cells.The process is characterized by changes at the cellular, genetic, and epigenetic levels and abnormal cell division.Cell division is a physiological process that occurs in almost all tissues and under a variety of circumstances. It is still accepted today that cancer originates in a single cell and develops through the clonal proliferation of their progeny.
