they are viruses that insert their DNA into random places inside the genome of the host. if the virus inserts itself into the promoter of a tumor suppressor, you end up making less of the tumor suppressor => you're in trouble

Oh...and what is a tumor suppressor exactly, an enzyme, something that repairs DNA?

There should be quite a lot of website discussing the effects of HPV considering the furore caused by some vaccination programs. But be careful, not everything is reliable...
