Testicular Cancer Risk Factors

Scientists have identified several risk factors for testicular cancer. Even if someone has a risk factor, it’s impossible to know how much it contributes to developing testicular cancer:

  • An undescended testicle: This means that one or both testicles fail to move from the abdomen into the scrotum before birth. Men with this condition are several times more likely to get testicular cancer than men with normal testicles.
  • Family history of testicular cancer: Having a close relative such as a father or brother with testicular cancer raises the risk.
  • HIV infection: Some evidence has shown that men infected with the HIV virus, particularly those with AIDS, are at increased risk.
  • Age: About half of testicular cancers occur in men between the ages of 20 and 34, but it can occur at any age.
  • Race and ethnicity: The risk of testicular cancer among white men is 4 to 5 times higher than for black men and Asian-American men.
