[Relationships between occupational exposure and cancer of the testis].

Prevalence of cancer of the testis has been increasing in recent decades. We studied risk of testicular cancer in relation to occupations and occupational exposures. A significantly increased risk of testicular cancer is associated with occupations in the agricultural, tannery and mechanical industries. Consistent associations with painting, mining, plastic and metal working, and occupational use of hand-held radar have been observed. Because of the small number of exposed subjects in some studies, results have been spurious in many cases and require further analysis.
