Genital warts are growths on the skin of the genital area and around the anus. They are caused by certain types of the human papilloma virus (HPV).
There are more than 100 types of HPV. Some types of HPV produce warts on different parts of the body, like plantar warts on the feet and common hand warts. Some can lead to certain cancers — these are called high-risk types of HPV. And some produce genital warts.
