[Epidemiology of penile cancer].

BACKGROUND

Penile cancer represents a rarity in daily clinical practice.

OBJECTIVES

The aim is to identify global differences concerning the incidence, social and risk factors.

METHODS

The past and current epidemiologic literature is analyzed concerning incidence rates and risk factors. The latter are discussed concerning their potential with regard to disease prevention.

RESULTS

Globally, incidence rates of penile cancer range from low to nonexistent. Distinct differences are found when comparing industrialized countries with emerging and developing countries. Phimosis seems to be a crucial risk factor in the formation of penile cancer. Additionally, chronic inflammatory diseases of the penis were found to be associated with a higher risk.

CONCLUSIONS

Preventive measures should be considered in relation to the rarity of the disease, especially in the valuation of circumcision during early childhood. Regular clinical examination of the penis is a sensible measure of early detection.
