A wart, or common wart, can be removed by medication, physical or surgical methods. Common warts are benign proliferative diseases caused by human papilloma virus infection of the skin mucous membranes, occurring on the fingers, back of the hand, foot margins, etc. Most of them can be eliminated naturally within five years, and they can also be treated by the use of medications such as salicylic acid ointment, peptide butyramide cream, pingyangmycin, imiquimod cream and other drugs, which are all required to be used under the guidance of a medical professional in order to avoid any adverse reactions. In addition, physical methods such as liquid nitrogen cryotherapy, laser, electrodesiccation and electrocautery can also remove common warts. Patients may also choose to undergo surgical excision, and sometimes special spatulas can be used to scrape off the warts. If you have common warts, it is recommended that you visit a hospital in time and follow the doctor’s instructions to receive standardized diagnosis and treatment.
