Yes, all warts are caused by HPV, or human papillomavirus, including genital warts. However, there are more than 150 types of HPV, and the types that cause warts on the hands or feet are not the same types linked to cancer.
Of these HPV types, about 40 can infect the genital area, and 12 are considered high-risk. These high-risk types can lead to cancer of the cervix, vulva, vagina, penis, anus, or oropharynx (throat), while the other types only cause warts.
Warts are benign growths that develop in the outer layers of the skin or mucous membranes. They happen when cells in the epidermis, the skin’s outermost layer, grow abnormally. The most common type is the common wart, which is usually raised, rough, whitish, and may have tiny black dots. These warts can appear anywhere on the skin and are very common in children.
Because several skin conditions can cause lesions that look like warts, it is important to see a dermatologist. A dermatologist can diagnose the type of lesion and recommend the most appropriate treatment.
