What are warts?

Classification of Warts
- Common warts: Usually appear on the hands, fingers, or around the nails. They typically have a rough surface and are skin-colored or slightly gray. This type of wart is easily spread through scratching, rubbing, or biting nails.
- Flat warts: These are small in size, with a less rough surface, and often grow in clusters on the face, neck, or back of the hands. Because they are difficult to identify with the naked eye, flat warts easily spread before treatment.
- Plant warts: These develop in pressure areas, causing pain when walking. Because they are pressed under the skin, this type of wart is often difficult to treat and easily mistaken for calluses.
- Genital warts: These appear on the genitals or anus, mainly transmitted through unsafe sexual contact. This type of wart requires early examination because it is associated with high-risk HPV strains. Fibrous warts: These are long, thin warts that often appear around the eyes, nose, or mouth. This type of facial wart grows rapidly, especially in people with weakened immune systems.
What causes warts?

Effective Ways to Treat Warts Completely
Treatment with Topical Medications
- Salicylic acid: Works by gradually removing the thick keratin layer, slowly eliminating wart tissue and killing the HPV virus. This process needs to be done regularly for several weeks to be effective.
- Imiquimod topical medication: Helps stimulate the local immune system, causing the body to recognize and destroy the HPV virus. This medication is often prescribed for flat warts or genital warts.
- Podofilox topical medication: Acts directly on the wart tissue, causing necrosis of virus-infected cells. It may cause a slight stinging sensation in the treated area.
- 5-fluorouracil topical medication: Helps inhibit cell division, stopping wart growth and causing it to gradually peel off. Cantharidin: Causes a controlled blistering reaction on the skin surface, helping to separate the pimple from healthy tissue and causing it to gradually peel off after a few days.

Treatment with Injections
- Bleomycin injections: Injected directly into the wart, destroying the virus-infected cells from within.
- Interferon injections: Help boost the local immune response, supporting the mechanism for controlling the HPV virus.
Intervention with Modern Medical Methods
- Cryotherapy: Uses liquid nitrogen to freeze and destroy wart tissue. After treatment, the damaged tissue will necrose and slough off over time.
- Electrocautery: Uses high-frequency electrical current to remove warts. This method is fast but requires proper wound care.
- Laser: Precisely targets wart tissue, destroying the blood vessels that nourish the HPV virus. Lasers are often used for papillomas and warts on the face.
- Surgical removal: Applied when warts are too large or do not respond to other methods. Post-treatment monitoring is necessary to minimize the risk of recurrence.
Preventing Wart Formation and Recurrence
- HPV vaccination helps reduce the risk of infection with common virus strains, especially genital warts.
- Avoid direct contact with the wart area to limit the possibility of infection.
- Do not touch or squeeze the warts as this can easily spread the virus.
- Do not share personal items to reduce the risk of indirect transmission.
