it is possible for an oncocyte [cancerous cell] to lose the features that define it as a subunit of tissue. in this case warts, or tumour cells may be transplanted during surgery, to a person that has nicked themselves with a scalpel or other such instrument, it is not impossible for a technician to have this happen while preparing a biopsy. the way a virus promotes cancer is by inserting, into genetic locus [address] that is close enough to the start of an "oncogene" that cancer results.
