What Are the Risk Factors for Testicular Cancer?

An exact cause of testicular cancer remains unclear. However, researchers have discovered a number of factors that may increase your risk for developing the cancer.

Having a risk factor does not mean you will develop testicular cancer. Risk factors for testicular cancer include:

  • An undescended testicle (cryptorchidism) or inguinal hernia when you were born
  • Testicles that did not develop normally
  • Previous testicular cancer. About 3% to 4% of those successfully treated for testicular cancer will develop cancer in the other testicle.
  • Carcinoma in situ of the testicle
  • HIV infection
  • Family history of testicular cancer, especially in a brother or father
  • Race. White cisgender men are 4 to 5 times more likely to develop testicular cancer than African-American or Asian-Americans.
