Penile cancer affects from 0.82 per 100,000 in Denmark to 10.5 per 100,000 men per year in parts of India (0.9 to 1 per 100,000 in the United States). Studies have reported a rate of penile cancer from 3 to 22 times higher in uncircumcised than circumcised men.
The American Academy of Pediatrics (1999) stated that studies suggest that neonatal circumcision confers some protection from penile cancer, but circumcision at a later age does not seem to confer the same level of protection. Further, because penile cancer is a rare disease, the risk of penile cancer developing in an uncircumcised man, although increased compared with a circumcised man, remains low.
I hate Wikipedia quoters, it just proves you know nothing about the topic, but facts are facts my friends.
Obviously circumcised.
