Follicular dendritic lymphoma and Co-carcinogenesis

Co-carcinogenesis: a virus and a carcinogen together cause cancer. Taking Francis Peyton Rous’ hypothesis further, the carcinogen is a polymerase inhibitor which binds the viral polymerase with higher affinity. Thus the DNA methylation state has been changed but the virus is no longer viable.  DNA damage does not cause most cancers, the interaction of carcinogens and viruses do.  Further these cancers wear the receptors that the virus that triggered it used to enter and the characteristics of the cancer will be from the receptor's pathways.

With the current popularity of Tattoos will this form of cancer increase?

In order for Cancer to occur the virus must trigger the cell division cycle.  Knudson's Retinoblastoma protein genes are the target of nuclear viral proteins.

Knudson's 2 hit RB cancer gene is the lynch pin to the cell division cycle start

(this form does not involve a viral start but most cancers will need a virus to pull this lynch pin)
