Welcome to IANS

We are the world's first professional society devoted to the prevention and treatment of AIN (anal intraepithelial neoplasia) and anal cancer.

Our mission is to provide a forum for individuals with a broad spectrum of backgrounds, viewpoints and geographic origin, an exchange of ideas and dissemination of knowledge regarding the pathogenesis, diagnosis, treatment and prevention of anal neoplasia.
