The incidence of a second primary testicular germ cell cancer in the contralateral testicle among 2338 men with a first primary testicular germ cell cancer diagnosed in the years 1960–79 in Denmark ...was established in this preliminary report. The material represents 83% of the total cohort followed until 31 December 1984. The relative risk for a patient with testicular cancer to get yet another testicular cancer was studied, taking into account the histology of the first primary testicular germ cell cancer. Based on fifty‐eight nonsimultaneous contralateral testicular cancer cases and 19,995 ‘person‐years at risk’, the overall relative risk of invasive germ cell cancer in the contralateral testicle following a first germ cell testicular cancer was found to be 23.3 (95% confidence interval. 18–30). Among men with nonseminoma the risk was higher (relative risk = 27.5) than among men with seminomas (relative risk = 20.1). Overall, sixty‐two (2.7%) patients developed a second cancer. In four of these patients bilateral tumours occurred simultaneously.
