Penile Cancer: Causes, Symptoms, and Diagnosis Explained

By 3 January 2026January 18th, 2026No Comments

This Ultimate Guide explains what penile cancer is and how it affects the penis. It sets out causes, common signs, how diagnosis works and what staging means.

Although the condition is rare, early-stage disease is more treatable. It usually begins in surface tissues, so spotting changes early and seeking assessment can improve outcomes.

The article will help readers recognise symptoms penile cancer may cause and describe what happens at a GP appointment. It also explains tests used to confirm diagnosis and how doctors assess spread.

Groin lymph nodes are key to checking whether the disease has moved beyond the original site. The guide covers penile-sparing approaches alongside wider options, and when extra therapies may be recommended.

The tone is practical and supportive, acknowledging embarrassment or stigma while encouraging prompt action. In the UK, specialist pathways and NHS centres exist to manage this rare condition effectively.

Key Takeaways

  • It is a rare form of cancer that starts in the penis’ surface tissues.
  • Early detection improves treatment choices and outcomes.
  • GP assessment, tests and node checks in the groin guide staging and care.
  • Treatment can spare tissue in some cases; wider therapy may be needed if spread occurs.
  • Specialist NHS centres and pathways exist across the UK for expert care.

Penile cancer explained: what it is and why it’s considered rare

Knowing the typical starting point and how often it occurs gives practical context to this rare condition.

Where it usually starts: skin and foreskin

This type of disease is an abnormal growth of cells that most often begins in the skin of the shaft or the foreskin. Early changes tend to stay on the surface before involving deeper tissues of the penis.

How rare it is in practice

Incidence is low — roughly 0.5 to 1 case per 100,000 males. That means it is far less common than many other cancers. Because of this rarity, signs can be missed and large studies are fewer than for common tumours.

Why early, local disease is easier to treat

When the problem is confined within the organ, treatment can be simpler and outcomes are generally good. If the disease shows evidence of cancer spread to lymph nodes or other parts body, planning becomes more complex and results may worsen.

If a persistent sore, lump or change to the penile skin does not heal, it should be checked promptly. For information on related risks such as HPV, see HPV information.

Signs and symptoms to look out for

Noticing a sore or lump that does not heal is the common first reason men seek assessment.

Common symptoms: lump, sore, bleeding, or discharge

Watch for: a lump, persistent sore or ulcer, unexpected bleeding or any discharge. These changes usually occur on the surface of the penis and may come with pain or scabbing.

Symptoms under the foreskin and tight foreskin

Lesions can appear at the foreskin edge or beneath it. A tight foreskin (phimosis) can hide early signs and make self-checks difficult.

If the foreskin will not retract and new symptoms develop, men should seek advice rather than trying to diagnose the problem themselves.

Groin lumps and lymph node involvement

A new lump in the groin may signal enlargement of nearby lymph nodes. That finding needs assessment because nodes can indicate spread beyond the primary site.

  • Persistent local symptoms warrant a GP appointment in the UK, especially if there is bleeding or discharge.
  • Delay is common — embarrassment, fear and low awareness mean many men wait 6–9 months, which can lead to a later stage at diagnosis.

Diagnosis cannot be made from symptoms alone, but early presentation helps clinicians plan examination and tests quickly. For related risk information see prostate hyperplasia treatment.

Causes and risk factors that may increase risk

Understanding which factors increase risk helps people and clinicians spot changes earlier and act promptly. Causes are not always identifiable for an individual, but recognised risk factors can guide prevention and earlier detection.

Human papillomavirus (HPV) and its role

HPV (human papillomavirus) is linked with some cases. It is a common virus and certain strains can contribute to abnormal cell changes on the penis.

This link is factual and non-judgemental: not everyone with HPV will develop disease, but vaccination and safe practices can lower risk.

Age and other linked factors

The condition mainly affects men aged over 50, although younger men can be affected. Age is a key factor that may increase the likelihood of diagnosis.

Other factors linked with higher likelihood include long-term irritation, poor hygiene in some situations and smoking. These are associations, not guaranteed causes.

Reducing risk: awareness and prompt assessment

“Treat any persistent skin change as worth discussing with a clinician.”

  • Check the penis regularly for new lumps, sores or discharge.
  • Seek prompt assessment — do not wait months for symptoms to settle.
  • Early detection keeps more treatment options available and may reduce the need for extensive surgery.

How penile cancer is diagnosed

A clear diagnostic pathway begins with history-taking and a hands-on clinical check of the penis and nearby skin. In the UK this usually starts at the GP surgery and may lead to rapid referral to a specialist clinic.

Clinical examination and what clinicians look for on the penis and skin

Clinicians inspect lesions for size, ulceration, colour and texture. They check for discharge, bleeding and any signs of infection that might mimic malignant change.

Palpation of the groin looks for enlarged lymph nodes. Findings at this stage shape which further tests are needed and how quickly a specialist review is arranged.

Biopsy and pathology: how cancer cells are confirmed under the microscope

Biopsy is the key step. A small sample is taken and sent to pathology, where tissue is examined under the microscope to identify cancer cells.

Pathology confirms the type of tumour, indicates aggressiveness and guides treatment. Results usually take days to a few weeks and will determine next steps.

“Any persistent sore or lump should be assessed — tissue diagnosis is essential.”

Assessing nearby healthy tissue and depth of involvement

Pathology and imaging assess margins and how deep the abnormal cells reach. Knowing whether healthy tissue borders the lesion helps plan organ-sparing treatment where possible.

Depth of involvement links directly to stage and choice of surgery. Clear communication of results ensures timely referral to multidisciplinary teams when specialist input is required.

Step Purpose Typical timeframe (UK)
Clinical history & examination Identify suspicious skin changes and groin nodes Same day to 2 weeks
Biopsy & pathology Confirm cancer cells and tumour type under the microscope 1–3 weeks
Imaging & margin assessment Evaluate depth, local spread and nearby healthy tissue 1–4 weeks

Staging and cancer spread: how penile cancer can move to other parts of the body

Staging describes how far abnormal cells have reached and sets the clinical plan for care. It is a standard way to state where the disease is and how widely it has spread. Stage informs treatment intensity and aims.

How spread happens and why nodes matter

The common route is via the lymphatic system. Drainage from the penis flows to inguinal (groin) lymph nodes and then to pelvic nodes. Around one-third of people present with metastases in these inguinopelvic lymph nodes, so node assessment is central to care.

Distant spread to organs

When cancer spread parts body beyond nodes, it may reach the lungs, liver, bones and brain. Distant metastases carry a worse outlook and usually require systemic therapy alongside local treatment.

Prognosis and next steps

Node-positive disease has lower survival: roughly 50% at three years and about 30% at five years. Higher nodal burden or organ spread worsens outcomes. Treatment may therefore combine surgery, node clearance and systemic therapy to try to control disease.

Early detection of node involvement improves the chance that surgery alone may be curative.

Feature Why it matters Implication for treatment
Localised (early stage) Confined to surface tissues Penile‑sparing surgery may be possible
Inguinopelvic nodes involved Shows lymphatic spread; ~33% at presentation Node dissection or sentinel biopsy; consider adjuvant therapy
Distant metastases Spread to lungs, liver, bones, brain Systemic treatment and palliative measures often needed

Lymph node tests in the groin, including sentinel lymph node biopsy

Testing the groin aims to find early lymph spread while avoiding unnecessary surgery. In suspected penile cancer, groin checks help decide whether small, targeted tests or larger node removal are needed.

What the sentinel node is and why it’s checked first

The sentinel lymph node is the first node that receives lymph drainage from the penis. It is most likely to contain any early spread, so checking it gives reliable staging information with minimal intervention.

How SLNB is performed

Sentinel lymph node biopsy is done under general anaesthetic. A small amount of blue dye and a harmless radioactive tracer are injected near the tumour.

Surgeons use the blue stain and a handheld detector for radioactivity to locate the target nodes. Those nodes are removed through a small groin incision and sent to pathology for analysis.

What results mean and next steps

If the sentinel node is negative, further groin node surgery is unlikely to be needed. If it is positive, surgeons usually recommend removing all nodes in the affected area to reduce the chance of spread.

“Sentinel testing balances thorough control with fewer complications than routine extensive node surgery.”

What patients can expect: a day-case or short stay, small scars, and clearer staging to guide treatment. These tests help clinicians plan the right level of care while reducing the risk of lymphoedema and other complications.

Treatment options for penile cancer

Treatment for this condition is tailored to the tumour, the node status and the person’s priorities.

Managing the primary tumour

Penile-sparing approaches aim to remove disease while keeping form and function where safe. Local excision, laser therapy or partial glansectomy may be used for small, superficial lesions.

More extensive surgery is reserved for larger or deeply invasive tumours. The exact choice depends on stage, location and tissue involvement.

Managing lymph nodes

Assessment and removal of groin lymph tissue are the second major pillar of care. Early lymph node dissection in node-positive disease is linked with improved disease-specific survival.

Radical node surgery can cause practical harms. These include infection, delayed wound healing and longer-term lymphoedema affecting the groin or legs.

Radiotherapy and chemotherapy

Radiotherapy or chemotherapy may be offered alongside surgery when pathology shows higher risk features or when spread is suspected.

These therapies can improve control beyond surgery alone, especially in advanced stage disease or when margins are close.

Multimodal treatment for advanced disease

When pelvic nodes, extranodal extension or N3 disease make surgery alone unlikely to cure, combinations of surgery, radiotherapy and systemic therapy are used.

2023 EAU‑ASCO guidance recommends offering adjuvant radiotherapy for pN2 and pN3 disease.

Balancing cure with side effects

Decisions should be made jointly, weighing cure rates, recovery time, sexual function and daily life impact.

  • Discuss likely benefits and risks of each option.
  • Plan wound care and lymphoedema prevention after node surgery.
  • Consider specialist input for rehabilitation and psychosocial support.

Care in the UK: specialist centres, multidisciplinary teams, and support

Specialist centres in the NHS bring together skilled clinicians to speed accurate assessment and improve outcomes. Since centralisation began in 2002, England runs nine supra‑regional centres that manage this rare condition.

How supra-regional centres support diagnosis and treatment

These centres see higher case volumes and provide detailed pathology, precise staging and experienced surgical teams. That expertise increases the chance of organ‑sparing surgery where safe.

Concentrated services also improve lymph node assessment and overall survival through standardised pathways and rapid access to imaging and biopsy.

Why multidisciplinary care matters for node-positive disease

Node‑positive disease is best managed by a multidisciplinary team. This brings together urology, oncology, radiology, pathology, specialist nursing and rehabilitation therapists.

Team decisions tailor treatment plans, balancing surgery, radiotherapy and systemic options to match disease extent and patient priorities.

Quality of life and practical support

Treatment can affect sexual function, voiding and body image. Stigma and emotional strain are common and deserve open discussion with clinicians.

Men and partners should be offered rehabilitation, counselling and early symptom management—not only after treatment ends.

Support services and resources

Practical support includes psychological services, lymphoedema care and peer networks. Reputable charities such as ORCHID and Maggie’s provide information and emotional support.

“Specialist centres and joined-up teams mean men get coordinated care and clearer access to rehabilitation and support.”

Service What it offers When to ask
Supra‑regional centre High‑volume surgery, detailed pathology, rapid staging After GP referral or specialist clinic appointment
Multidisciplinary team Joint planning of surgery, radiotherapy and systemic treatment When nodes are involved or staging is complex
Support services Psychological support, lymphoedema therapy, peer groups At diagnosis, during treatment and in follow‑up

Conclusion

Quick medical review of any persistent penile symptom often keeps treatment less invasive and more successful. This condition is rare, yet early-stage penile cancer is usually more treatable than disease that has spread.

Watch for key symptoms: a lump, a sore that won’t heal, bleeding or unusual discharge. Changes may hide beneath the foreskin, especially with phimosis, so check carefully.

Diagnosis follows examination, biopsy and confirmation of cancer cells by pathology, then staging to guide treatment. Groin lymph nodes are vital: node status strongly affects prognosis and further care.

If disease spreads to other parts of the body management becomes more complex. In the UK, seek a GP review for any worrying change, attend specialist referrals and use charity and NHS support. Timely action improves options and outcomes.

FAQ

What is the condition and why is it considered rare?

This disease affects the skin of the penis, often starting on the glans or under the foreskin. It is classed as rare because it occurs far less often than many other male cancers, with only a small number of new cases each year in the UK and similar countries.

Where does it usually start?

Most tumours begin on the shaft or tip of the organ, or beneath the foreskin. Lesions may appear as a lump, sore, scaly patch or ulcer on the skin and can be mistaken for benign conditions.

How does rarity affect diagnosis and treatment?

Low incidence means fewer specialists and centralised care pathways. Treatment and diagnosis are concentrated in supra‑regional centres with multidisciplinary teams to ensure experience with these uncommon cases.

What are the common early signs and symptoms to watch for?

Early signs include a persistent lump, non‑healing sore, bleeding, unusual discharge or changes to skin colour or thickness. Any persistent change should prompt assessment by a GP or specialist.

What symptoms occur specifically under the foreskin?

Under the foreskin there may be swelling, discharge, or a sore that is hard to see. A tight foreskin (phimosis) can hide symptoms and delay diagnosis, making regular checks and prompt medical review important.

What do lumps in the groin indicate?

Swollen groin nodes often suggest lymphatic involvement. Enlarged inguinal glands can mean that abnormal cells have spread from the primary tumour into nearby lymph nodes.

Why do some men delay seeing a GP and what is the impact?

Stigma, embarrassment and lack of awareness lead some to delay. Later presentation increases the chance of more advanced disease and can limit organ‑sparing treatment options.

What role does human papillomavirus (HPV) play?

Certain high‑risk HPV types are linked with many cases. HPV can cause abnormal cells that, over time, may progress to invasive disease in a minority of men.

Which other risk factors increase likelihood?

Risk rises with age, especially over 50, and with poor genital hygiene, phimosis, smoking and certain chronic inflammatory skin conditions.

How can men reduce their risk?

Awareness, regular self‑examination, prompt GP review for changes, smoking cessation and HPV vaccination where recommended can reduce risk or aid early detection.

How is the condition diagnosed clinically?

Diagnosis starts with a clinical examination of the penis and groins. Specialists assess the lesion’s size, location and any lymph node enlargement before arranging further tests.

What does a biopsy involve and why is pathology important?

A biopsy removes a small tissue sample for microscopic analysis. Pathology confirms the presence of abnormal cells, determines type and grade, and guides treatment decisions.

How is the extent of local tissue involvement assessed?

Clinicians evaluate the lesion’s depth and whether it invades nearby healthy tissue. Imaging such as ultrasound or MRI may help assess local spread and plan surgery.

What does staging mean and how does it affect treatment?

Staging describes tumour size, local invasion and nodal or distant spread. It guides treatment choices: early stages may be managed conservatively, while advanced stages often need multimodal therapy.

How does spread through lymphatics occur and why are groin nodes important?

Malignant cells travel via lymphatic vessels to inguinal and pelvic nodes. The status of these nodes strongly influences prognosis and determines whether extended node surgery is needed.

Can the disease spread beyond lymph nodes and to which organs?

In advanced cases cells can metastasise to distant organs such as the lungs, liver, bones and, less commonly, the brain. Such spread requires systemic treatment and specialist input.

What is a sentinel lymph node and why test it?

The sentinel node is the first node likely to contain spread from the primary tumour. Testing it helps identify microscopic nodal disease without immediate removal of many nodes.

How is a sentinel lymph node biopsy performed?

Surgeons inject a dye and/or radioactive tracer near the tumour to map lymphatic drainage. Under general anaesthetic they remove the sentinel node(s) for pathological examination.

What do sentinel node results mean for further surgery?

A positive sentinel node often leads to more extensive lymph node dissection. A negative result can spare the patient from wider groin surgery and its complications.

What local treatment options preserve the organ?

Where feasible, organ‑sparing techniques include wide local excision, laser therapy or glans resurfacing. These aim to remove disease while maintaining function and appearance.

When is partial or total removal necessary?

Larger or deeply invasive tumours may require partial or total removal of the organ to achieve clear margins and reduce risk of recurrence.

How are affected lymph nodes managed surgically?

Early lymph node dissection may be recommended for confirmed nodal disease. Surgery reduces tumour burden but carries risks such as wound complications and lymphoedema.

When are radiotherapy and chemotherapy used?

Radiotherapy may treat local disease or nodal areas. Chemotherapy is used for advanced or metastatic disease and sometimes as part of combined‑modality treatment for bulky nodal disease.

What is multimodal treatment for advanced disease?

Advanced cases often require a combination of surgery, radiotherapy and chemotherapy to control local disease and distant spread, especially in extensive nodal (N3) situations.

How are side effects balanced with chances of cure?

Clinicians and patients discuss trade‑offs: more aggressive treatment can improve survival but increases risks such as infection, delayed wound healing and chronic lymphoedema. Individual values guide choices.

How does specialist multidisciplinary care improve outcomes?

Supra‑regional NHS centres bring together urologists, oncologists, radiologists, pathologists and specialist nurses. Team planning improves staging accuracy, treatment selection and supportive care.

What support is available for quality‑of‑life issues?

Services include sexual health counselling, continence advice, psychological support, lymphoedema therapy and peer support through charities such as Orchid and Macmillan.

When should a man see a specialist about changes?

Any persistent lump, sore, bleeding or discharge should prompt a GP visit and, if needed, rapid referral to a specialist centre for assessment and possible biopsy.
