Testicular Cancer: Symptoms & Signs

Testicular (testes) cancer is a malignant tumor that begins in the testes, or testicles, of a male. It is most common in men between the ages of 20 and 35. There are different types of testicular cancer, but most start in the germ cells (that form sperm).

Signs and symptoms of testicular cancer can include

  • a painless lump or swelling in either testicle,
  • a change in texture of the testicle or how it feels, or
  • a sudden buildup of fluid in the testicle or scrotum, leading to swelling of the scrotum.

Testicular cancers do not cause pain that comes on suddenly, but dull ache in the lower abdomen of groin may be present.
