Penile cancer is very rare in Europe and North America, occurring in about one in 100,000 men in the latter. It accounts for 0.2% of cancers and 0.1% of deaths from cancer amongst males in the United States. However, in some parts of Africa and South America it accounts for up to 10% of cancers in men.<ref name="What Are the Key Statistics About Penile Cancer?">{{REFweb
