Only 1% of all male tumors are testicular origin, but it is the most frequent neoplasia in younger men. Risk factors include cryptorchism and a positive personal history of testicular cancer. Testicular cancer is divided in germ cell cancer and non germ cell cancer, the latter accounting for about 5%. Germ cell cancer is classified in seminoma and nonseminoma. Usually the first clinical presentation is painless swelling. Afterwards ultrasonography is indicated and tumor markers should be analysed. The first therapeutic step is always a radical inguinal orchiectomy. The following treatment depends on the staging: wait and see, radiotherapy or chemotherapy. Testicular cancer is characterised by a good cure rate (98-100% early stages) or recurrence free survival (80-90% late stages).
