What is the most common age at which men develop penile cancer?

Depends: Penile cancer is usually caused by the papilloma virus and is nearly always found in men not circumcised at birth. It can be found in men in their 30s, especially in countries where men are not routinely circumcised and hygiene standards are lower. In the United States, most men diagnosed are elderly.

Older men: Penile cancer is a rare disease in the us and developed countries, and tends to be a disease of older men. The incidence of penile cancer is rare before 50, increases abruptly in men aged 60 years or older (60% greater than 65), and peaks in men aged over 70. However, early onset is possible. Some reports of men diagnosed in their 30's and 40's.
