The reality is more ambiguous.
Circumcised men get penile cancer at about the same tiny rate as intact men.
When men of the same ages were compared, the correlation vanished. It would be erroneous to conclude from this that circumcision tends to cause penile cancer. Other factors, such as different prevalence of smoking in the two countries, may account for the difference. Circumcision is the removal of a part or all of the foreskin at birth or later on in life. This practice has been suggested as conferring some protection against cancer of the penis by contributing to improved hygiene.
