What is a lump on the testicle (scrotal mass)?

A lump on the testicle, or a scrotal mass, can form in your scrotum (the pouch of skin containing the testicles). It can be a symptom of other medical conditions, most of which aren't serious. The majority of scrotal masses are benign (not cancerous) and don't pose a risk to your health.

Some, however, can affect fertility in men, and in rare cases, be a sign of a serious condition such as cancer. That's why your healthcare provider should examine any lump you may discover in your scrotum.

Where would a lump on my testicle be, and what would it feel like?

Lumps can be located anywhere around the testicles and vary in size. Some can be as small as a pea or marble, but some can grow larger.

Most lumps are soft and fluid-filled and may make your scrotum look a little swollen; these are usually harmless and often go away without treatment. Some lumps are solid and may feel attached to one of your testicles. Harder lumps can be a sign of something more serious.

If you feel lumps or swelling, let your provider know.
