Denmark, while it has one of the lowest rates of penile cancer for a non-circumcising country, nevertheless has 10x the rate of penile cancer as Israel – where almost all men are circumcised.  Likewise, a Kaiser Permanente study of patients with penile cancer found that 16% of patients with carcinoma in situ had been circumcised; only 2% of patients with invasive penile cancer had been circumcised.  Since the circumcision rate of Kaiser patients of the appropriate age was ~50%, this is in line with the 90% reduction.
