We encourage you to discuss with your health care provider any questions or concerns that you may have.  


 Although testicular cancer is rare, it is the most common cancer for American males between the ages of 15 and 35. It is highly treatable, especially when discovered at an early stage.


  • An undescended testicle.       (The majority of men who develop testicular cancer don’t have a history of undescended testicles.)
  • Abnormal testicle development. Family history. If family members have had testicular cancer, you may have an increased risk.
  • Age. Although testicular cancer can occur at any age, it mostly affects males between the ages of 15 and 35.
  • Race. Testicular cancer is most common in Caucasian men.


  • A lump or enlargement in either testicle
  • A feeling of heaviness in the scrotum
  • A dull ache in the abdomen or groin
  • A sudden collection of fluid in the scrotum
  • Pain or discomfort in a testicle or the scrotum
  • Enlargement or tenderness of the breasts
  • Back pain

Testicular cancer usually affects only one testicle.

See your health care provider if you detect any pain, swelling or lumps in your testicles or groin area, especially if these signs and symptoms last longer than two weeks. Your health care provider may refer you to an urologist and/or an oncologist.


Currently, there is no evidence on strategies to prevent testicular cancer, but early detection can increase the possibility of successful treatment. Some health care providers recommend regular testicle self-examination so that you become familiar with your testicles and aware of any changes.

How to do a Testicular Self Examination:

  • Stand in front of a mirror.       Look for any swelling on the skin of the scrotum.
  • Examine each testicle with both hands. Place the index and middle fingers under the testicle while placing your thumbs on the top.
  • Gently roll the testicle between the thumbs and fingers. Remember that the testicles are usually smooth, oval shaped and somewhat firm.       It’s normal for one testicle to be slightly larger than the other. Also, the cord leading upward from the top of the testicle is a normal part of the scrotum.
  • If you find a lump, make an appointment with your health care provider.
