Flat warts are caused by human papillomavirus (HPV) infection. Under a physician’s guidance, topical medications—such as fluorouracil ointment or imiquimod cream—may be applied. If topical treatment proves ineffective, patients may seek physical therapies at a hospital, including carbon dioxide laser therapy and liquid nitrogen cryotherapy.
