Anal warts


anal wartAnal warts are caused by the human papillomavirus (HPV), which has been linked to increased risk of cervical and anal cancers. Infection occurs when secretions collect in the anal area, causing multiple warts of various sizes. Although individuals who engage in anal intercourse have a higher frequency of perianal warts, the majority of patients with perianal warts have not engaged in anal intercourse.

Anal warts can be treated with agents such as topical Fluorouracil (Efudex) and Imiquimod (Aldara), but they have a low cure rate. Trichloroacetic acid (TCA) and cryotherapy with liquid nitrogen are more successful but may require several treatments, especially with large lesions. Radiofrequency and laser therapy produce 90 percent cure rates and is the preferred treatment method by Dr.Shu.
