Testicular Cancer Facts

What is testicular cancer?

Cancer starts when cells start to multiply and grow out of control. Testicular cancer forms in the testicles, which produce sperm and the hormone testosterone.
 
Testicular cancer is highly curable, with survival rates well over 90 percent, especially if detected and treated early. Although it is a rare cancer, this disease is still the leading cause of cancer in young men in their 20s and 30s.

Testicular cancer risk factors

There are several factors that may increase your risk of developing testicular cancer:
  • Undescended testicle. One of the main risk factors for testicular cancer is having an undescended testicle.
  • Age. Approximately half of testicular cancer cases are found in men in their 20s and 30s.
  • Race and ethnicity. White men have a higher risk for testicular cancer.
  • Cancer in the other testicle. Men who have had testicular cancer in one testicle are at higher risk for getting it in the other one.
  • Family history. Having a father or brother with testicular cancer increases the risk that you will get it as well.
  • HIV infection. Men infected with HIV may have a higher risk for developing testicular cancer.

What are Testicular cancer signs and symptoms

Possible testicular cancer warning signs may include:
  • An uncomfortable, but not necessarily painful lump on your testicle
  • Swelling or enlargement of a testicle
  • Heaviness or aching in the scrotum or abdomen
  • Tenderness or swelling in the breasts
