Testicle lumpLump in the testicle; Scrotal mass
A testicle lump is swelling or a growth (mass) in one or both testicles.
A testicle lump that does not hurt may be a sign of cancer. Most cases of testicular cancer occur in men ages 15 to 40. It can also occur at older or younger ages.
Possible causes of a painful scrotal mass include:
- A cyst-like lump in the scrotum that contains fluid and dead sperm cells (spermatocele). (This condition sometimes does not cause pain.)
- Infection of the scrotal sac.
- Injury or trauma.
- Orchitis (testicular infection).
- Testicular torsion.
- Testicular cancer.
Possible causes if the scrotal mass is not painful:
- Loop of bowel from a hernia (this may or may not cause pain)
- Testicular cancer
- Cyst of epididymis or testicle
Starting in puberty, men at risk for testicular cancer may be taught to do regular exams of their testicles. 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
If you have a lump in your testicle, tell your health care provider right away. A lump on the testicle may be the first sign of testicular cancer. Many men with testicular cancer have been given a wrong diagnosis. Therefore, it is important to go back to your provider if you have a lump that doesn't go away.
When to Contact a Medical Professional
Call your provider right away if you notice any unexplained lumps or any other changes in your testicles.
What to Expect at Your Office Visit
- When did you notice the lump?
- Have you had any previous lumps?
- Do you have any pain? Does the lump change in size?
- Exactly where on the testicle is the lump? Is only one testicle involved?
- Have you had any recent injuries or infections? Have you ever had surgery on your testicles or in the area?
- What other symptoms do you have?
- Is there scrotal swelling?
- Do you have abdominal pain or lumps or swelling anywhere else?
- Were you born with both testicles in the scrotum?
Tests and treatments depend on the results of the physical exam. A scrotal ultrasound may be done to find the cause of the swelling.
