Testicular Lump: Causes, Symptoms & When to See a Doctor

Not necessarily. While a painless lump in the testicle can be a sign of testicular cancer, it's important to note that most painless lumps are not cancerous. There are many other potential causes of painless testicular lumps, such as:

* Epididymitis: inflammation of the epididymis, a tube that connects the testicle to the vas deferens

* Spermatocele: a cyst filled with sperm

* Hydrocele: a collection of fluid around the testicle

* Testicular torsion: a twisting of the testicle

* Inguinal hernia: a protrusion of the abdominal contents into the groin

If you're concerned about a lump in your testicle, it's important to see a doctor for an evaluation. The doctor can perform a physical exam and order imaging tests, such as an ultrasound, to determine the cause of the lump.
