If you experience any of these symptoms do not assume it is due to cancer. Most of these symptoms may be caused by other, less serious health conditions. If you experience any one of them, see your physician.

Symptoms of testicular cancer include the following:

  • A painless lump or swelling in either testicle—this is the single most important symptom of testicular cancer. If you detect this, see your doctor immediately.
  • Enlargement or swelling of a testicle, or a change in the way it feels.
  • Feeling of heaviness in the scrotum.
  • A dull ache in the lower abdomen or groin.
  • Fluid in the scrotum that appears suddenly.
  • Pain or discomfort in a testicle or in the scrotum.
  • Lower back pain, sometimes severe (in later stages, when the cancer has spread into the lymph nodes in the back).
  • Shortness of breath, chest pain, or coughing up blood (in advanced stages, when the cancer has spread into the lungs).
  • Enlarged breasts (due to alterations in sex hormone production).

The best way to discover testicular cancer is by finding it yourself when it is small. You can do this with regular testicular self-exams. As with all cancers, the best results come from early treatment.
