HPV usually spreads during sexual intercourse with an infected partner. Some HPV-caused lesions on the cervix are associated with an increased risk of cervical cancer. Symptoms usually appear from three weeks to eight months after exposure. It is advisable to use condoms if there is any question of prior exposure. The visible genital warts start as small painless hard spots which appear on the bottom of the vaginal opening.
Warts also occur on the labia, vulva, cervix, anus and male genitalia.
Warmth and moisture encourage the growth of warts which develop a cauliflower appearance as they grow larger. It must be applied only by a physician. Chemical burns of the surrounding skin must be avoided. Sometimes several treatments are necessary, and they are not always successful. Often 12 - 16 weeks are required for treatment, but it can be used at home by the patient.
