Testicular Disease in Busan, Korea

The testicles can be affected by pain, swelling, lumps and infections — from harmless cysts and varicoceles to infections (epididymitis, orchitis) and, importantly, testicular cancer, which is most common in younger men and highly curable when caught early.

TL;DR — quick answer

The testicles can be affected by pain, swelling, lumps and infections — from harmless cysts and varicoceles to infections (epididymitis, orchitis) and, importantly, testicular cancer, which is most common in younger men and highly curable when caught early.

What is testicular disease?

The testicles can be affected by pain, swelling, lumps and infections — from harmless cysts and varicoceles to infections (epididymitis, orchitis) and, importantly, testicular cancer, which is most common in younger men and highly curable when caught early.

Any new lump, swelling or persistent pain in the testicle should be checked promptly. Evaluation is quick and usually reassuring, but the small number of serious causes are exactly why it should not be ignored.

Causes

  • Infection (epididymitis, orchitis)
  • Varicocele (dilated scrotal veins)
  • Cysts and benign swellings
  • Injury or torsion (twisting — an emergency)
  • Testicular tumours (must be excluded)

Symptoms

  • A lump or swelling in a testicle
  • Testicular pain or aching
  • A feeling of heaviness in the scrotum
  • Sudden severe testicular pain (emergency)
  • Swelling with fever (possible infection)

Self-check: should you get this looked at?

  • You have found a lump or swelling
  • There is new or persistent testicular pain
  • One testicle feels heavier or different
  • You have swelling with fever
  • You noticed a change during self-examination

If several of these apply to you, a urological evaluation is worthwhile. This checklist is a guide, not a diagnosis.

Accurate diagnosis

How we diagnose it

Examination

A careful scrotal examination assesses lumps, swelling and tenderness.

Scrotal ultrasound

Ultrasound is the key test to characterise a lump and distinguish benign from serious causes.

Urinalysis & blood tests

Testing checks for infection and, where relevant, tumour markers.

Urgent triage

Sudden severe pain is assessed urgently to exclude torsion.

Treatment

How we treat testicular disease

Treat infections

Epididymitis and orchitis are treated with appropriate antibiotics and supportive care.

Manage benign conditions

Cysts and varicoceles are monitored or treated depending on symptoms and fertility plans.

Prompt cancer pathway

If a tumour is suspected, we refer urgently for treatment — testicular cancer is highly curable when caught early.

Emergency referral

Suspected torsion is a surgical emergency and is escalated immediately.

Testicular problems are evaluated promptly and thoroughly here, with ultrasound to separate the common benign causes from the few serious ones, by a board-certified urologist. English-speaking support keeps a worrying symptom clearly explained, and urgent findings are escalated fast.

Frequently asked

Questions from foreign patients

Most testicular lumps are benign, but any new lump should be checked promptly. Ultrasound quickly clarifies the cause, and testicular cancer is highly curable when caught early.

Yes — it can indicate torsion, a surgical emergency. Seek care immediately.

A varicocele is a dilation of scrotal veins that can cause aching and sometimes affect fertility. We assess whether it needs treatment.

With examination and a scrotal ultrasound, plus urine and blood tests where relevant.
