Knowing what the symptoms of testicular cancer are increases the likelihood of finding the disease in its early stages. In some cases, men may discover a lump accidentally or during a routine self-examination. If you do notice an unusual lump or experience other testicular cancer symptoms, it is important to talk with your doctor.

Some signs of a testicular tumor are also associated with non-cancerous conditions. Your doctor may run further tests to identify the cause of the lump or other symptoms, and to determine the correct treatment, if necessary.

Common signs of cancer that develops in the testicles include:

  • Hard lumps or nodules on either testicle or a change in how the testicle looks or feels
  • Swelling in the scrotum, sometimes caused by a sudden build-up of fluid
  • A dull ache in the lower abdomen or the scrotum
  • Pain, discomfort or a feeling of heaviness in the scrotum
  • Enlarged or swollen breasts caused by the secretion of hormones that stimulate breast growth by the testicular tumor

Some testicular cancers do not produce any symptoms at all. A variety of non-cancerous conditions produce symptoms similar to a testicular tumor, such as testicular injury and inflammation, and viral or bacterial infections. It is important to discuss testicular cancer symptoms you are experiencing with a doctor who can help you understand what condition, if any, you may have.
