Question: what does it mean when you have lumps on your balls?
Answer: Share on Pinterest Testicle lumps may be caused by cysts, hydroceles, and epididymitis. A cyst is a fluid-filled sac that can feel like a small, hard lump when touched. Cysts can develop almost anywhere on the body and are usually harmless. A varicocele is a lumpy area caused by swollen veins in the testicles.
