Testicular Cancer | Causes & Risk Factors


Who gets testicular cancer?

Cancer of the testicles is rare, but it is the most common cancer in young men (15 to 34 years old). If you are a man, you are more likely to get testicular cancer if you:

  • Are white.
  • Have a father or brother who has or has had testicular cancer.
  • Have a testicle that did not come down into the scrotum (called an undescended testicle). This is true even if surgery was done to remove the testicle or bring it down.
  • Have small testicles or testicles that aren't shaped normally.
  • Have Klinefelter's syndrome (a genetic condition where male infants are born with an extra X chromosome).
