Testicular Cancer

Each year, more than 9,500 men are diagnosed with testicular cancer, and more than 400 die of the disease. Although men of any age may develop testicular cancer, it is most frequently diagnosed in men ages 20-34.

Testicular cancer is usually curable when found early and treated appropriately; treatment is often successful even at later stages.

You might be at increased risk for testicular cancer if you:

  • Had an undescended testicle(s) at birth or other abnormal development of the testes
  • Are infected with human immunodeficiency virus (HIV)
  • Have a genetic problem caused by having an extra X chromosome
  • Have a personal or family history of testicular cancer
  • Are white

Talk with your health care professional right away if you have any of these symptoms:

  • A painless lump, enlargement or swelling in either testicle
  • A change in how the testicle feels
  • Dull aching in the lower abdomen, back or groin
  • Pain or discomfort in a testicle or in the scrotum
  • Sudden collection of fluid in the scrotum
  • Feeling of heaviness in the scrotum

If you have a son who was born with an undescended testicle, talk with his health care professional about correcting it before he reaches puberty.

  • Ask your health care professional to examine your testicles as part of your routine physical exam.
  • Talk with your health care professional about testicular self-exam. It is one way to get to know what is normal for you. If you notice a change, talk with your health care professional right away.
