It has long been known that in
population groups where circumcision is performed e.g.
-Jews and Muslims - cancer of the cervix is rare and penile
cancer almost nonexistent. In recent years the role of
human papilloma virus (HPV) in both penile and cervical
cancer has been proven, and these cancers are now being
thought of as sexually transmitted diseases. A recent
study of over 1900 couples in 5 countries found that penile
HPV infection is about 3 times as common in uncircumcised
males as in circumcised males and there is about a 2.5
fold increased risk of cervical cancer in women whose
sexual partner is uncircumcised and has had multiple partners.
