Cause

 * The exact cause is unknown.


 * Smegma, a cheese-like, foul-smelling substance found under the foreskin of the penis may increase the risk of penis cancer.


 * Uncircumcised men who do not keep the area under the foreskin clean and men with a history of genital warts or human papillomavirus (HPV) are at higher risk for this rare disorder.
