Growth-like viral infection of the skin.
Warts are caused by the human papilloma viruses, a.k.a., HPV, which come in numerous different types. Certain types of HPV cause growths that are associated particularly with the genitals. Certain types of HPV also can give rise to cervical cancer as well as cancers of the penis, portions of the throat (oropharynx), etc.
