The surgery is done to remove or destroy anal warts if other treatments, like applying medicines, are unsuccessful or not advised. Surgery may also be ideal if there are many warts or if the warts are large. If warts are not removed, they can become bigger and multiply. Warts may also lead to an increased risk of cancer in the affected area.
