Testicular Tumors | Symptoms & Causes

What are the symptoms of testicular tumors?

Testicular tumors are often noticed when a growth develops on one of the testes. Keep in mind that the symptoms of a testicular tumor may resemble other more common conditions or medical problems. It is important to consult your child's physician for a diagnosis.

Testicular tumor symptoms may include:

  • swelling in the affected testicle
  • a hardened mass on the affected testicle
  • abnormal shape of the testicle or irregularity in size between testicles
  • testicular pain (though some tumors are painless)

What causes testicular tumors?

Doctors do not completely understand the cause of most testicular tumors. Scientists do know that certain germ-cell tumors can be associated with a number of other inherited defects of the central nervous system, genitourinary tract, and lower spine. Boys with undescended testicles have an increased risk of developing certain germ cell tumors.
