Urethral Cancer
Introduction
Urethral cancer is rare and occurs in both sexes; it may be squamous or transitional cell carcinoma or, occasionally, adenocarcinoma. 50. Certain strains of Human Papillomavirus (HPV) Infection have been implicated in certain cases. Urethral tumors invade adjacent structures early and thus tend to be advanced when diagnosed. External groin or pelvic (obturator) lymph nodes are usually the first sites of metastasis.
