Anal Warts


anal wartAnal warts are growths found around the anus, in the anal canal, or in the lower rectum. Anal warts are caused by the human papilloma virus, which is usually transmitted through sexual contact but not always through anal intercourse. These may also occur on the penis, scrotum, vagina or labia. It usually takes one to six months, but sometimes longer, for the warts to appear after being exposed to the virus. There are many types of human papilloma virus—some cause warts on the hands and feet while other types cause genital and anal warts.

There are often no symptoms at all. Sometimes there may be small growths in the anal area or minor itching, bleeding, or moisture in the anal area.

It depends on the location, number, and size of the warts. Small 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.
