Testicular cancer epidemiology and demographics

Prevalence and distribution
Testicular cancer is most common among Caucasians and rare among African Americans. Testicular cancer is uncommon in Asia and Africa. Worldwide incidence has doubled since the 1960s, with the highest rates of prevalence in Scandinavia, Germany, and New Zealand.

Incidence among African Americans doubled from 1988 to 2001 with a bias towards seminoma. The lack of significant increase in the incidence of early-stage testicular cancer during this timeframe suggests that the overall increase was not due to heightened awareness of the disease.

Although testicular cancer is most common among men aged 15-40 years, it has three peaks: infancy, ages 25-40 years, and age 60 years.

Germ cell tumors of the testis are the most common cancer in young men between the ages of 15 and 35 years.
