Overview

Penile cancer is a malignant growth that arises from tissues of the penis, most commonly the skin of the glans or foreskin. It is an uncommon disease in many high-income settings but remains more frequent in some low- and middle-income regions. Early recognition and prompt evaluation improve chances for cure.

Causes and risk factors

The exact cause of any individual case varies, but several factors increase risk. Human papillomavirus (HPV) infection is a well-established contributor. Other associations include chronic inflammation or poorly controlled foreskin conditions, tobacco use, and conditions that interfere with hygiene. Circumcision in infancy appears to lower the risk in some studies, though it is not an absolute protector.

Signs, diagnosis and staging

Common presentations include a visible lesion, persistent ulcer, bleeding, or a lump on the penis. Regional lymph node enlargement may be the first sign in some patients. Definitive diagnosis requires a tissue biopsy and pathological analysis. Imaging and clinical examination are used to determine local extent and nodal involvement, which guide staging and treatment planning.

Treatment options

  • Local therapies: topical agents and limited excision for very early lesions.
  • Surgical options: wide local excision, partial or total penectomy depending on extent; lymph node evaluation or dissection when indicated.
  • Radiation and systemic chemotherapy: used for organ preservation in select cases or advanced disease.
  • Reconstructive surgery and psychosocial support are important parts of care.

Prevention and public-health notes

Prevention strategies emphasize HPV vaccination, smoking cessation, good genital hygiene, and access to timely medical evaluation for suspicious lesions. Awareness of differences in incidence between regions highlights the role of social and health-system factors in outcomes. For general information about cancer and anatomy of the penis, see reliable public resources; epidemiologic patterns vary between developed countries and developing countries.

Notable facts

Prognosis strongly depends on stage at diagnosis: localized disease is often curable, while advanced disease has a more guarded outlook. Multidisciplinary management—combining urology, oncology, pathology, and supportive services—improves outcomes and quality of life.
