ABSTRACT
BACKGROUND: No analytic epidemiological study has examined the relationship between use of muscle-building supplements (MBSs) and testicular germ cell cancer (TGCC) risk. METHODS: We conducted a population-based case-control study including 356 TGCC cases and 513 controls from Connecticut and Massachusetts. RESULTS: The odds ratio (OR) for ever use of MBSs in relation to risk of TGCC was significantly elevated (OR=1.65, 95% confidence interval (CI): 1.11-2.46). The associations were significantly stronger among early users, men with more types of MBSs used, and longer periods of use. CONCLUSIONS: MBS use is a potentially modifiable risk factor that may be associated with TGCC.
