Plantar warts can be treated by surgical excision, but surgical excision of plantar warts is often suspected of malignancy or other treatment failure, not recommended to arbitrarily carry out. 1. The treatment of plantar warts includes medication, physical therapy and surgery. If you suspect malignancy, or if other treatments fail, surgery may be considered, and a biopsy is usually required to further define the nature of the wart. 2. However, it should be noted that surgery is not a routine treatment for plantar warts. Surgery is not recommended because it can cause scarring, recurrence and scar contracture, and may even prevent walking. It is advisable to go to the hospital and choose the right treatment for your plantar warts under the guidance of a professional doctor.
