Growths in the scrotum or testicles may be noncancerous (benign) or
cancerous (malignant).
- The scrotum has many large oil (sebaceous) glands
on the skin. These may form
cysts the size of marbles that feel like painless
lumps. They may drain white, greasy material (sebum). Sebaceous cysts can
become infected and painful.
- Growths in the
epididymis may be caused by kinks in the epididymis
itself or may occur following a
vasectomy. Painless lumps ranging from the size of BBs
to marbles may form. These usually are not serious. When the epididymis becomes
inflamed or infected (epididymitis), it feels like a swollen tubular mass
behind the testicle. Epididymitis usually causes pain and
tenderness.
- A distended, enlarged vein (varicose vein) in the
scrotum is called a
varicocele. It may be uncomfortable. A varicocele can
cause a low sperm count. If infertility is a concern, the varicocele may need
to be surgically removed. Otherwise, a varicocele is usually left
alone.
- A buildup of fluid in the sac that surrounds the testicle is
called a
hydrocele.
- Testicular cancer is
most common in men between the ages of 15 and 35. A tumor is often felt as a
painless, hard lump inside or on the testicle. It may become painful if it
spreads into the epididymis.
Any new growth in the scrotum or testicles should be evaluated by
your health professional.
