Testicular lump or swelling

What the symptom means

The scrotum contains the testicles and nearby structures, so a lump or swelling can come from several places. Some causes are harmless; others need treatment. A clinician can usually narrow this down with an examination and an ultrasound.

Common categories of causes

Possible causes include benign cysts, fluid collections around the testicle, enlarged veins, infection or inflammation, and, less commonly, testicular cancer. A painless lump within the testicle is particularly important to have checked.

What a clinician may ask

Expect questions about when you noticed the change, whether it is painful, any recent injury or infection, and other symptoms. A scrotal ultrasound is commonly used to look more closely.

Safe self-care boundaries

Do not wait to see if a new lump goes away. Regular self-awareness helps you notice changes early, but it does not replace a clinical assessment of anything new.

Questions to ask a clinician

• What is the likely cause of my lump or swelling?
• Do I need a scrotal ultrasound?
• Which symptoms would mean I should seek urgent care?
• What are the next steps if further tests are needed?
