Penile cancer is uncommon, but a persistent ulcer, growth, thickened area, bleeding lesion or change on the glans/foreskin should not be ignored. Most penile cancers are squamous cell carcinomas. Diagnosis requires careful examination and usually biopsy. Early-stage disease can often be treated with organ-preserving approaches, while larger or invasive tumours may require partial or total penectomy. The groin lymph nodes are crucial because penile cancer commonly spreads first to the inguinal nodes; timely nodal staging and treatment can strongly influence cure.

Possible symptoms

• Non-healing ulcer or sore
• Raised, warty or cauliflower-like growth
• Thickened or discoloured area on the glans or foreskin
• Bleeding or foul-smelling discharge
• Progressive phimosis or inability to retract the foreskin
• Palpable groin lump
• Pain is possible but early lesions may be painless

Risk factors

Important associations include persistent phimosis, chronic inflammatory penile disease, smoking and infection with oncogenic HPV types. Circumcision in childhood lowers risk mainly by preventing phimosis and chronic inflammation, but adult circumcision is not a guarantee against cancer.

How is penile cancer diagnosed?

The urologist examines the entire penis and both groins. Biopsy confirms the diagnosis and grade. MRI or other local imaging may be used when depth or corporal invasion is uncertain. Groin-node assessment is risk-based because clinically normal nodes can still contain microscopic metastases.

Treatment of the primary tumour

Superficial disease may be treated with topical therapy, laser or glans-preserving excision in selected cases. Invasive lesions may require glansectomy, partial penectomy or occasionally total penectomy. The goal is complete cancer control while preserving length, urinary function and sexual function whenever oncologically safe.

Why groin nodes matter

Nodal stage is one of the strongest determinants of outcome. Enlarged nodes may be inflammatory or metastatic, while normal-feeling nodes do not always exclude microscopic spread. Dynamic sentinel-node biopsy or inguinal lymph-node dissection may be recommended according to primary tumour risk and node findings.

Why normal-feeling groins can still need staging

No palpable groin lump does not guarantee that the nodes are clear. In higher-risk primary tumours, microscopic inguinal metastases can be present before nodes become enlarged enough to feel or see reliably on routine imaging. This is why dynamic sentinel-node biopsy or inguinal lymph-node dissection may be recommended in selected clinically node-negative patients. The aim is to detect nodal disease while it is still potentially curable rather than waiting for a large groin mass to appear.

A biopsy should precede destructive treatment of a suspicious lesion

Persistent ulcer, growth, induration or bleeding should not be repeatedly cauterised or treated as infection without a diagnosis. Biopsy confirms squamous-cell carcinoma and provides grade and other features that help determine how much tissue must be removed and whether groin staging is needed.

Penile preservation is an oncological objective when safe

For superficial or smaller distal tumours, options may include topical treatment for selected premalignant disease, laser, glans resurfacing, glansectomy or other organ-preserving surgery. The aim is complete cancer control with as much useful penile tissue as possible; preservation should not mean accepting inadequate margins or undertreating invasive disease.

What treatment may mean for urination and sexual function

Functional impact depends mainly on how much tissue must be removed and where the tumour lies. Superficial treatments and glans-preserving operations may retain standing urination and useful sexual function, while partial penectomy can shorten the penis and alter the direction of the urinary stream. Total penectomy creates a perineal urinary opening. These consequences should be discussed before treatment whenever there is time, but preservation must never come at the cost of leaving invasive cancer behind.

Groin management can determine cure

The most important prognostic step after control of the primary tumour is often assessment of inguinal lymph nodes. Higher-risk primary tumours can harbour microscopic nodal disease even when the groins feel normal. Timely nodal staging is therefore part of treatment, not merely follow-up.

When to seek earlier medical review

Arrange prompt review for a persistent penile ulcer, growth, bleeding, foul discharge, new phimosis or a groin lump. Difficulty passing urine, uncontrolled bleeding or rapidly progressive infection/swelling needs urgent care.

What to bring to your consultation

• Biopsy/HPE report if done
• Photographs showing change over time if available
• CT/MRI/PET staging reports
• Current medicines and prior penile procedures

Questions to ask your doctor

• What does the biopsy show about grade and depth?
• Can the primary tumour be treated with organ-preserving surgery safely?
• Do clinically normal groins still need staging in my risk group?
