Key points
- Penile cancer is a rare but serious condition primarily affecting the skin and glans of the penis.
- Early detection is critical, as localized penile cancer is highly treatable with conservative measures.
- Common symptoms include persistent sores, changes in skin thickness, or unexplained discharge under the foreskin.
- Risk factors include being over 50, smoking, and chronic inflammation due to phimosis.
- A UK GP should review any new penile growth or persistent skin change within two weeks.
- Online doctor services can provide initial assessment and referral advice for those worried about symptoms.
What is Penile Cancer?
Penile cancer is a rare form of cancer that develops in the skin or tissues of the penis. In the UK, it affects approximately 600 to 700 men annually, according to NHS data. While rare, it is a significant condition because early-stage diagnoses are often manageable with treatments that preserve as much function and appearance as possible. Conversely, delayed diagnosis can lead to more invasive surgery.
Most cases are squamous cell carcinomas, occurring on the glans (head) of the penis or under the foreskin. Because it often starts as a small skin change, it can be mistaken for a fungal infection, dermatitis, or a sexually transmitted infection (STI), which is why clinical review is vital for any lesion that does not heal within two to three weeks.
Recognising the Symptoms
Primary Signs to Monitor
- A Growth or Sore: This is the most common symptom. It may appear as a small bump, a wart-like growth, or a flat ulcer. It generally does not heal despite using over-the-counter creams.
- Bleeding or Discharge: Unexplained bleeding or a foul-smelling discharge from under the foreskin should always be investigated.
- Skin Changes: Thickening of the skin, change in colour (redness, brown patches, or white spots), or the skin becoming velvety to the touch.
- Phimosis: If the foreskin becomes difficult to pull back, it may be due to a growth underneath or chronic inflammation (balanitis xerotica obliterans), which increases cancer risk.
It is important to note that many of these symptoms are caused by benign conditions. However, under NHS and NICE guidance, any persistent lesion on the penis requires a 'two-week wait' referral to a urologist if cancer cannot be ruled out during a physical examination.
Risk Factors and Prevention
While any man can develop penile cancer, certain factors increase the likelihood. In the UK, the following are considered significant risk factors:
- Human Papillomavirus (HPV): Certain high-risk strains of HPV are linked to nearly half of all penile cancer cases. The HPV vaccine, now offered to boys in UK schools, significantly reduces this risk.
- Age: It is most common in men over 50, though it can occur at any age.
- Smoking: Chemicals in tobacco can damage cell DNA in the penis, especially when concentrated in secretions near the glans.
- Poor Hygiene and Phimosis: If the foreskin is tight (phimosis), it is harder to clean underneath. The buildup of smegma and chronic inflammation can lead to cancerous changes over many years.
- Treatment for Psoriasis: Some PUVA (psoralen plus ultraviolet A) treatments used for skin conditions have been linked to a slightly increased risk.
When to Speak to an Online Doctor in the UK
Many men feel embarrassed about penile symptoms, leading to delays in seeking help. An online doctor in the UK can offer a discreet first step for assessment. If you notice a new lump, a change in skin texture, or a sore that hasn't cleared up with standard treatments (like antifungal creams for thrush), a consultation is necessary.
During a digital consultation, a GP can discuss your medical history, symptoms, and risk factors. They can advise on whether your symptoms are likely related to an infection or if they require an urgent in-person physical examination. In cases where a lump is present, the GP will likely recommend an immediate face-to-face appointment with a local clinic or hospital for palpation and potential referral to a urology specialist for a biopsy.
How is Penile Cancer Diagnosed?
If a GP suspects penile cancer, they will follow NICE (National Institute for Health and Care Excellence) guidelines for an urgent referral. The diagnosis process usually involves:
- Physical Examination: A urologist will examine the penis and feel the lymph nodes in the groin for any swelling.
- Biopsy: A small tissue sample is taken under local or general anaesthetic to look for cancer cells. This is the only definitive way to diagnose the condition.
- Imaging: If cancer is confirmed, MRI or CT scans may be used to see if the disease has spread to the lymph nodes or other parts of the body.
Early diagnosis often allows for 'organ-sparing' surgery, laser therapy, or topical chemotherapy, which carries a high cure rate and maintains quality of life.
Living with Penile Concerns
Most penile lumps and bumps are not cancerous. Conditions like pearly penile papules, Fordyce spots, or molluscum contagiosum are common and benign. However, the anxiety of not knowing can be distressing. Regular self-examination (checking once a month during a shower) is the best way to stay aware of what is normal for your body. If you are unsure, do not wait for the symptom to go away on its own. Seeking pro-active advice from a healthcare professional ensures that if treatment is needed, it is started as soon as possible.
Red flags — when to seek urgent help
Call 999 or go to A&E if you experience any of the following:
- A rapidly growing, painful lump on the penis.
- Sudden, heavy bleeding from the penis or under the foreskin.
- Hard, swollen lumps in the groin area (lymph nodes) that do not go away.
- A sore or ulcer that starts to emit a very strong, unpleasant odour.
