With very stubborn or very large genital warts, surgical removal may be necessary. The patient's sexual partner should also be examined for warts by a dermatologist. Warts may be very difficult to cure. Occasionally multiple treatments will be needed and even then treatment success cannot be guaranteed. There have been many new treatment advances developed recently.
Laser therapy is one of the newer methods used to destroy some types of warts.
But it is more expensive and requires the injection of a local anesthesia to numb the area beforehand. Another treatment is for warts to be injected individually with an anti-cancer drug called bleomycin. Unfortunately, the injections may be painful. Another new method is immunotherapy, which attempts to build up the body's own rejection system. Several methods of immunotherapy are being used, but the most common is one in which the patient is literally made allergic to a certain chemical.
