Prevalence and risk factors for anal human papillomavirus infection in human immunodeficiency virus HIV -positive and high-risk HIV-negative women.
As a result, parts of this article may be outdated. Because of the high prevalence of AIN in certain populations, some researchers have advocated foregoing cytology and using HRA as a primary screening test. By calculating the effect of different screening strategies including no screening on lifetime costs, life expectancy, and quality-adjusted life expectancy for this population, Dr. ASIL is usually asymptomatic although occasionally patients complain of pain, pruritis, bleeding, discharge, or tenesmus.

Surgical destruction is usually reserved for individuals with extensive disease who require an examination under anesthesia and multiple biopsies to rule out invasive cancer.
