What is Penile cancer?
Penile cancer is a rare cancer that develops in the tissue of the penis, most commonly on the foreskin or head. It typically starts as a change in the skin, such as a growth, sore, or discolouration, that doesn't heal.
Risk factors include HPV infection, phimosis (a tight foreskin that's difficult to retract), smoking, and poor genital hygiene. Early diagnosis significantly improves treatment outcomes, so any unusual, persistent changes should be checked.

Practical steps
Take these self-care steps
These measures can help ease symptoms, support recovery, and reduce the chance of things worsening — but they don't replace medical advice if symptoms are severe or persistent.
- 1Don't delay getting checked.Any unusual, persistent change to the skin of the penis should be assessed by a doctor promptly, even if it seems minor.
- 2Practise good genital hygiene.Regularly and gently washing under the foreskin can help reduce the risk of infection and irritation.
- 3Consider HPV vaccination where eligible.Since HPV is linked to penile cancer risk, vaccination can help reduce the chance of infection.
- 4Avoid smoking.Smoking is a known risk factor for penile cancer, so quitting can help reduce your overall risk.

BarnMD Bottom Line
Penile cancer is rare, and most changes in the genital area are due to less serious causes, but early assessment of anything unusual gives the best outcome if it is cancer.
Any sore, lump, or skin change on the penis that doesn't heal within a few weeks should always be checked by a doctor.
