TESTICULAR CANCER

INCIDENCE AND EPIDEMIOLOGY

Annual incidence is about 9560 cases with 410 deaths. Peak age incidence is 20–40. Occurs 4–5 times more frequently in white than black men. Cryptorchid testes are at increased risk. Early orchiopexy may protect against testis cancer. Risk is also increased in testicular feminization syndromes, and Klinefelter syndrome is associated with mediastinal germ cell tumor.
