They are immortalize: Programmed cell death is markedly reduced in cancer due to a phenomenon related to prolongation of chromosomal integrity. Normal cell that divide have caps on the top on the tops of their chromosomes known as telomeres. With each division, the telomere is reduced until the cell can not divide any further. Cancer has an enzyme known as telomerase that constantly replace the telomeres.
