Cancer is a disease of the genome. And that's what happens. You make mistakes in a cell somewhere in your body that causes it to start to grow when it should've stopped, and that's cancer. And those mistakes are mistakes of DNA.
Genomics is a new idea. Like the PC, it's not obvious at first that anyone would want one. It's like, 'Hey, we've already got one genome, why do we need more?'
I didn't want my genome to be sequenced by any of the companies that were out there doing the partial sequences just from the point of view of commercialisation.
