Considerations

A testicle lump that does not hurt may be a sign of cancer. Most cases of testicular cancer occur in men ages 15 - 40, although it can also occur at older or younger ages.

Causes

Possible causes of a painful testicle include:

Possible causes if the testicle is not painful:

  • Hydrocele
  • Loop of bowel from a hernia
  • Spermatocele
  • Testicular cancer
  • Varicocele

When to Contact a Medical Professional

Call your health care provider right away if you notice any unexplained lumps or any other changes in your testicles.

What to Expect at Your Office Visit

Your health care provider will perform a physical examination, which may include inspecting and feeling (palpating) the testicles and scrotum. The health care provider may ask questions about the lump, such as:

  • When did you notice the lump?
  • Have you had any previous lumps?
  • Do you have any pain?
  • Does the lump change in size?
  • Is only one testicle involved?
  • Exactly where on the testicle is the lump?
  • Have you had any recent injuries or infections?
  • What other symptoms do you have?
  • Is there scrotal swelling?
  • Do you have abdominal pain?
  • Do you have any lumps or swelling anywhere else?
  • Have you ever had surgery on your testicles or in the area?
  • Were you born with both testicles in the scrotum?

Tests and treatments depend on the results of the physical examination.

Prevention

Starting in puberty, men at risk for testicular cancer should examine their testicles on a regular basis. This includes men with:

  • A family history of testicular cancer
  • A past tumor of the testicle
  • An undescended testicle, even if the testicle on the other side has descended

These men should perform a testicular self-exam each month, so that a testicular lump can be found early. A lump on the testicle may be the first sign of testicular cancer.
