Anal 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.
Your doctor will inspect the skin around the anus and check the anal canal in order to make a diagnosis.
