Specialist assessment of testicular and scrotal lumps with same-day ultrasound. Same-week appointments routinely available.
Most scrotal lumps are not cancerous. Common benign causes — epididymal cysts, varicoceles, hydroceles, and inflammation — account for the majority of lumps assessed in urology clinics. However, a small but important minority of men have testicular cancer, which is the most common cancer in men aged 15–35 and exceptionally curable when caught early.
Any new lump, swelling, heaviness, or change in a testicle should be assessed within days, not weeks. A scrotal ultrasound — quick, painless, and highly accurate — distinguishes between cancer and benign conditions in the great majority of cases at a single appointment. Mr Haldar offers same-week consultation, usually with same-day ultrasound, at his clinics for patients from across Buckinghamshire, Berkshire, West Herts, London and Oxfordshire.
Urgent attention needed: if you have sudden severe testicular pain, with or without nausea or vomiting, attend A&E immediately or call 999. Testicular torsion is a surgical emergency — irreversible damage can occur within 6 hours.

Why a Rapid Access Scrotal Lumps Clinic Matters
Finding a lump in your testicle is frightening. Most men who notice one go through a brief period of intense worry, often made worse by reading online about cancer before knowing whether the lump is anything to worry about at all.
The clinical reality is reassuring: most scrotal lumps are not cancer. Common benign causes include:
- Epididymal cysts — fluid-filled lumps next to the testicle (very common)
- Varicoceles — varicose veins of the scrotum
- Hydroceles — fluid collection around the testicle
- Spermatoceles — sperm-containing cysts
- Inguinal hernias — extending into the scrotum
- Inflammation — epididymitis or orchitis (often after infection)
- Lipomas, fibromas, and other benign growths
However, a small but important minority of lumps are testicular cancer. A scrotal ultrasound makes it straightforward to distinguish benign from malignant lumps, which is why this clinic exists: to give you a clear, evidence-based answer within days.
A new lump or swelling in the testicle should be assessed urgently, ideally within days.
When You Should Seek Assessment
You should arrange a urological assessment for any of:
- A new lump or swelling in one testicle
- A change in size, shape, or firmness of a testicle
- Heaviness or dragging sensation in the scrotum
- A lump that has appeared above or behind a testicle
- A persistent ache in the testicle, scrotum, or groin
- A new collection of fluid in the scrotum
- Asymmetry between the two sides
- Any change you have noticed, however small, that does not settle within a few days
The single most important rule: do not wait to see if it goes away. Most lumps that need treatment do not resolve spontaneously, and if cancer is the cause, time genuinely matters.
Urgent (Same-Day) Attention
Some scrotal presentations are surgical emergencies. Attend A&E or call 999 immediately if you have:
- Sudden severe testicular pain — testicular torsion is a 6-hour surgical emergency
- Severe pain with nausea or vomiting
- A scrotum that has become very red, swollen, and tender
- Pain that woke you from sleep
- Scrotal injury with significant pain or swelling
- Fever with scrotal pain
Do not wait for a private appointment in any of these situations — go straight to A&E. Testicular torsion, in particular, can lead to permanent loss of the testicle within hours.
Common Causes of Scrotal Lumps
The most useful starting point is understanding what you may be feeling. The location and character of a lump often suggest the diagnosis, although an ultrasound is needed to confirm.
Lumps Within the Testicle
| Lump | Typical Features |
|---|---|
| Testicular cancer | Firm, painless, often within the testis itself; may distort the normal egg-shape |
| Epididymo-orchitis | Tender, often with redness and swelling; usually associated with infection |
| Testicular trauma / haematoma | Recent injury; tender; resolves over weeks |
Lumps Around the Testicle (Outside the Testis Itself)
| Lump | Typical Features |
|---|---|
| Epididymal cyst | Soft, smooth, separate from the testicle (usually behind or above); common and benign |
| Spermatocele | A type of epididymal cyst containing sperm; usually painless |
| Hydrocele | Painless fluid collection around the testicle; often soft and translucent on examination |
| Varicocele | Feels like “a bag of worms”; more prominent on standing or straining; often on the left |
| Inguinal hernia | Lump that extends into the scrotum from the groin; often reduces when lying down |
| Lipoma of the cord | Soft, painless lump along the spermatic cord |
Important Distinction
A confident clinical examination can usually distinguish whether a lump is inside the testicle (concerning) or separate from the testicle (usually benign). However:
- Some testicular cancers can present subtly
- Some benign lesions can feel firm
- The only reliable way to be certain is a scrotal ultrasound
This is why ultrasound is part of every assessment in this clinic, regardless of the clinical examination findings.
Testicular Cancer — The Important Minority
Around 2,400 men in the UK are diagnosed with testicular cancer each year. While most scrotal lumps are not cancerous, testicular cancer is:
- The most common cancer in men aged 15–35
- Painless in most cases at presentation — absence of pain does not mean benign
- Highly curable when caught early — overall 5-year survival exceeds 95%, and exceeds 99% for Stage I disease
The classic presentation is a painless, firm lump within the testicle itself, often noted incidentally during showering, examination, or sexual activity. Any such lump warrants prompt assessment.
If a testicular cancer is identified at the consultation, Mr Haldar provides continuity of care — moving you directly into the testicular cancer pathway, with surgery (radical orchidectomy) typically arranged within 1–2 weeks. See the Testicular Cancer page for full information on the pathway from diagnosis through surgery to follow-up.

Common Benign Conditions in Detail
Epididymal Cysts
The most common scrotal lump in adult men. They form within the epididymis — the structure that sits behind and above the testicle. Epididymal cysts are:
- Almost always benign
- Usually painless, sometimes uncomfortable if large
- Frequently multiple and bilateral
- Felt as smooth, fluid-filled lumps separate from the testicle
Most epididymal cysts need no treatment. Reassurance after ultrasound confirmation is usually sufficient. Surgery is occasionally considered for large, painful, or persistently troublesome cysts.
Varicoceles
Varicose veins of the scrotum are usually on the left (due to the way the left testicular vein drains). Common — affecting around 15% of adult men.
Symptoms:
- A feeling of fullness or “bag of worms”
- Heaviness or dragging, particularly after long periods of standing
- More prominent when standing or straining; reduces when lying down
- Occasional dull ache
When to consider treatment:
- Persistent pain or discomfort
- Reduced fertility or abnormal semen analysis
- Significant testicular shrinkage (atrophy) on the affected side
- Adolescent varicocele with a growth difference between the testicles
Treatment options include surgical varicocele ligation or radiological embolisation; many varicoceles need no treatment at all.
Hydroceles
A collection of fluid around the testicle, within the layers of the tunica vaginalis. Common in:
- Newborns and young infants — most resolve spontaneously by age 1–2
- Older men — often idiopathic; sometimes follows infection, trauma, or surgery
Features:
- Painless scrotal swelling
- Often translucent on examination (transilluminates with a light)
- Can become large but usually not dangerous
- Confirmed on ultrasound
Treatment is required only if the hydrocele is large, uncomfortable, or a source of concern. Surgery (Lord’s or Jaboulay procedure) is the definitive treatment; aspiration is occasionally used, but recurrence is common.
Epididymo-orchitis
Inflammation of the epididymis, the testicle, or both — usually due to infection.
Features:
- Painful, swollen testicle, usually on one side
- Redness and warmth of the scrotum
- Fever and feeling generally unwell
- May follow a urinary tract infection or sexually transmitted infection
Treatment is with antibiotics, but it is essential to distinguish epididymo-orchitis from testicular torsion, which presents with sudden, severe pain and is a surgical emergency. Ultrasound is often used in this distinction.
Inguinal Hernias
A weakness in the abdominal wall allowing tissue (usually bowel or fat) to extend into the inguinal canal and sometimes down into the scrotum.
Features:
- Lump that appears with standing, coughing, or straining
- Often reduces when lying down
- May extend from the groin into the scrotum
- Discomfort or dragging feeling
Inguinal hernia is treated by general or specialist hernia surgeons; Mr Haldar will refer to an appropriate colleague if a hernia is identified.
What Happens at the Clinic
1. Detailed History
A 30–45 minute consultation reviewing when the lump was noticed, any associated symptoms, history of trauma, infection, sexual activity, family history of testicular cancer, and any previous urological problems.
2. Examination
Careful examination of both testicles, the spermatic cord, the inguinal canals, and the abdomen. The position, size, character, and tenderness of the lump are assessed alongside the rest of the scrotal anatomy.
3. Scrotal Ultrasound
Ultrasound is the single most important investigation for any scrotal lump. It:
- Distinguishes solid from cystic lesions
- Identifies tumours within the testicle
- Confirms the diagnosis of epididymal cysts, hydroceles, and varicoceles
- Assesses blood flow (important for distinguishing torsion from epididymitis)
- Examines the unaffected side as a comparison
In the great majority of cases, ultrasound provides a definitive answer at the same appointment.
4. Blood Tests (Where Indicated)
If testicular cancer is suspected on examination or ultrasound, tumour markers are taken at the same visit:
- AFP (alpha-fetoprotein) — raised in non-seminoma germ cell tumours
- Beta-hCG (human chorionic gonadotrophin) — raised in some testicular cancers
- LDH (lactate dehydrogenase) — non-specific marker of tumour bulk
These are not always raised in testicular cancer, but they are part of standard staging if cancer is identified.
5. Diagnosis and Plan
At the end of the consultation, you will leave with:
- A clear diagnosis in the great majority of cases
- Reassurance if the lump is benign
- Onward referral if the lump is not urological (e.g. hernia)
- Direct continuation into treatment if the lump is testicular cancer

Frequently Asked Questions
I’ve found a lump — how worried should I be?
The best answer is: most scrotal lumps are not cancerous, but every new lump should be assessed promptly to be sure. Conditions like epididymal cysts, varicoceles, and hydroceles are common and benign. However, because testicular cancer is the most common cancer in men aged 15–35 and is highly curable when caught early, any new lump should not be ignored. Aim to be assessed within a few days, not weeks.
Can a scrotal lump be cancer if it doesn’t hurt?
Yes — and most testicular cancers are painless. The absence of pain does not mean a lump is benign. This is one of the most important facts about testicular cancer: men sometimes wait too long because they assume a painless lump can’t be serious. Any new painless lump in the testicle warrants assessment.
Does pain mean it’s not cancer?
Not necessarily. While most testicular cancers are painless, around 10–15% present with pain or discomfort. Pain can also occur with bleeding into a tumour or with associated infection. Pain does not exclude cancer, just as the absence of pain does not confirm benign disease.
What if my GP has already examined me and said it’s nothing?
GPs do an excellent job in distinguishing most benign and concerning scrotal findings. However, scrotal ultrasound is more accurate than examination alone, and some testicular cancers can be missed clinically. If you remain concerned or if the lump persists, a specialist consultation with a same-day ultrasound provides definitive reassurance.
What does a scrotal ultrasound involve?
Ultrasound is quick, painless, and uses no radiation. A small probe is gently moved over the scrotum after applying a small amount of gel, with images appearing on a screen in real time. The examination usually takes 10–15 minutes and provides immediate results.
Is a scrotal lump always treated?
No. Many benign lumps — particularly small epididymal cysts and asymptomatic hydroceles — need no treatment beyond confirmation that they are benign. Treatment is reserved for lumps that are painful, growing, causing functional problems, or when cancer is identified.
What if it’s testicular cancer?
If testicular cancer is identified, you remain under Mr Haldar’s direct care. Surgery (radical orchidectomy) is typically arranged within 1–2 weeks and is usually a day-case procedure performed via a small inguinal (groin) incision. Survival rates are excellent — over 95% overall, and over 99% for Stage I disease. See the Testicular Cancer page for full information on the pathway.
What is testicular torsion, and how is it different from a lump?
Testicular torsion is sudden, severe pain caused by the testicle twisting on its blood supply. It is a surgical emergency requiring same-day surgery — irreversible damage to the testicle can occur within 6 hours. Torsion is not a lump; it is acute pain. Do not wait for a private appointment if you have sudden severe testicular pain — go to A&E or call 999.
How quickly can I be seen?
Same-week appointments are routinely available at all clinic sites, with same-day ultrasound usually available at Chiltern, Princess Margaret, and GenesisCare Windsor for urgent cases. For Shelburne or Beaconsfield, an ultrasound is arranged at one of the full-service sites within the same week. If your situation is more urgent, please mention this when booking.
Should I do regular self-examination?
Yes. Every man should know what his testicles normally feel like, so any change can be spotted promptly. Monthly self-examination after a warm bath or shower (when the scrotum is relaxed) is a simple habit that can lead to earlier diagnosis of any concerning change. The Testicular Cancer page includes a step-by-step self-examination guide.
Can young boys and adolescents be seen at this clinic?
Adolescents aged 16 and over can be seen directly. For boys under 16, please see the Paediatric Urology Clinic page — children of all ages can be assessed for scrotal swellings, undescended testes, and hydroceles in that clinic.
Do I need a GP referral?
Many self-pay patients can self-refer. Most private medical insurers require a GP referral letter before authorising consultation or investigations — please check with your insurer before booking.
Do you accept private medical insurance?
Yes. Mr Haldar is recognised by all major UK private health insurers, including BUPA, AXA Health, Aviva, Cigna, Vitality Health, WPA, and Standard Life. Most insurers cover consultations, ultrasounds, and surgical fees, subject to your policy terms. See the Fees and Insurance page for details.
