How to remove flat warts on the hands

The main methods for removing flat warts on the hands include: 1. **Medication treatment**: Topical medications such as tretinoin cream, imiquimod cream, and fluorouracil ointment can be used. These medications act directly on the flat warts and help promote regression of the warts. Additionally, immunomodulators such as bacillus Calmette-Guérin (BCG) polysaccharide nucleic acid injection may be administered via injection to enhance immune function and aid in the treatment of flat warts. 2. **Physical therapy**: This includes cryotherapy and laser therapy. Cryotherapy uses the low temperature of liquid nitrogen to cause necrosis and shedding of the warts. Laser therapy involves directly burning or cutting the affected area with a laser, promoting necrosis of the diseased tissue. These physical methods can effectively and quickly remove flat warts. 3. **Surgical treatment**: For larger flat warts or cases unresponsive to medication or physical therapies, surgical excision may be considered. Surgical approaches may involve removing the flat warts and transplanting them into the subcutaneous fat layer, stimulating the body to produce viral antibodies and spontaneously eliminate the virus.
