Under a circumcision the penile prepuce is cutting off and cylindrical or columnar epithelium of a glans is afterwards transforming into the squamous epithelium. In uncut men the penile cylindrical epithelium is a proper place for cancerogenic types of human papillomaviruses (HPV) to persist and cause penile, anorectal, oropharyngeal and cervical cancer both in males and females under some circumstances. In USA where most men are cut a statistical rate of the fatal diseases is the lowest worldwide. So the circumcision cuts down prevalence of many HPV-linked pathologies as well as other sexually transmitted diseases. Many men around the globe are afraid of circumcision as if the procedure may cut shot their penises or cut down their sexual function. They'd wanted to cut that (ie. circumcision) out completely! However, the viewpoint cuts across a American Academy of Paediatrics policy, which similar to a vaccination policy arguing that the benefits of infant circumcision outweigh any risks.
