If those interested in all this would please read the HPV page they would understand all this. It is the virus's ability to express tow onco proteins E6 and E7 that allow it to live and control a normal cell without killing it, all the daughter cells spun off from that controlled cell will have the genetic mutations caused by those two proteins already in them, group a bunch of these together over a period of time and you have a tumor.

These oncoproteins destroy two key chromosomes, P53 that controls normal programed cell death ( apoptosis) making the cell essentially immortal, and the other turns off gene RB, a tumor suppressor gene making it invisible to the immune system. It is all very interesting, the trick is to interrupt this process or prevent it from starting. An antibody that recognizes the virus will destroy it before this genetic alteration can take place. Once that has happened though, it is what it is at our stage of understaning all this.
