We are gradually beginning to understand how different parts of our DNA are activated and deactivated to create what is called the epigenome and that it is the epigenome that is behind the differentation into our different body cell lines and their susceptibility towards becoming cancerous.
Merlin Crossley, Dean of Science and Professor of Molecular Biology at UNSW Australia has written one of the most lucid explanations about this process and how we are gradually untangling how it all happens. I can highly recommend his article:
