Testicle lump

Definition

A testicle lump is a swelling or mass in one or both testicles.

Alternative Names

Lump in the testicle

Considerations

A testicular lump that doesn't hurt may be a sign of cancer. Most cases of testicular cancer occur when men are between ages 15 and 40, although it can happen at older or younger ages.

Causes

Here are some possible causes of a painful testicle:

Injury or trauma
Epididymitis
Infection of the scrotal sac
Mumps
Orchitis (testicular infection)
Testicular torsion
Testicular cancer
Spermatocele (a cyst-like mass within the scrotum that contains fluid and dead sperm cells)
Varicocele (a varicose vein along the spermatic cord)

Here are some possible causes if the testicle is not painful:

Testicular cancer
Hydrocele (fluid collection in the scrotum)
Varicocele
Spermatocele
Loop of bowel from a hernia
