Risk Factors
- Orchiopexy--surgical placement of an undescended testis. The risk factor
here is the scrotal surgery, not the procedure itself.
- Age--most common in young adults 20-40 years
- Race--whites are 6 times more likely to develop testicular cancer than
blacks
- Vasectomy--surgical separation of the seminal vesicles for contraception.
The risk factor here is the scrotal surgery, not the vasectomy.
- Testicular trauma--crushing injury, blunt trauma (such as getting knee'd
in the groin) and other accidental injuries; risk of cancer is not known
but is under investigation.
- Other--orchitis (inflammation of the testicle); irradiation
- Men with a history of hernia
- Men with extra nipples
- Men with a history of infertility problems
- Men with cryptochidism or undescended testes,
which is the failure of one or both testicles to descend from the pelvis
(about 10 percent of men with testicular cancer have a history of cryptorchidism)
