Testicular Cancer Risk Factors

Certain factors can increase the risk of developing testicular cancer, including:
  • Undescended testicle (cryptorchidism) - Normally, the testicles descend from inside the abdomen into the scrotum before birth. The risk of testicular cancer is increased in males with a testicle that does not move down into the scrotum. This risk does not change even after surgery to move the testicle into the scrotum. The increased risk applies to both testicles.
  • Congenital abnormalities - Men born with abnormalities of the testicles, penis or kidneys, as well as those with inguinal hernia (hernia in the groin area, where the thigh meets the abdomen), may be at increased risk.
  • History of testicular cancer - Men who have had testicular cancer are at increased risk of developing cancer in the other testicle.
  • Family history of testicular cancer - The risk for testicular cancer is greater in men whose brother or father has had the disease.
