Primary<unk>  is rare and contributes to less than 1% of all cancers. It is three times more common in men than women and its incidence rises after the age of 75. Around half of affected people have locally advanced disease when they first present. 54–65% of cases are of the urothelial carcinoma type. Prolonged irritations of the urethra due to urinary catheterization, chronic inflammation due to infection, radiation, diverticula of the urethra, and urethral strictures, may increase the risk of primary<unk> . Other risk factors include squamous cell carcinoma (SCC) and genital lichen sclerosus.
