Marked differences in the incidence of testicular cancer have been observed in relation to geographical area, ethnicity and time period. The authors of this Review examine the available data and discuss the trends observed in the incidence of seminoma and nonseminoma in different populations. Causes of, and risk factors for, testicular cancer and the reasons behind observed increases in incidence are also discussed.
