What should you know about laser for warts?

A wart is a viral skin growth that may be rough, thickened, or clustered. Depending on the device, laser energy can heat wart tissue or treat blood vessels supplying it. The area may become tender, crusted, or swollen during healing, and more than one treatment may be considered. A clinician may first check whether the lesion is truly a wart, particularly if it bleeds, changes, or has an unusual appearance. Other options include [Cryotherapy (Lesion Removal)](/treatments/surgical-dermatology/cryotherapy-lesion-removal/) and [Electrosurgery](/treatments/surgical-dermatology/electrosurgery/).

Tell the clinician about diabetes, poor circulation, immune suppression, medicines that affect bleeding, and a history of thick scars. Do not shave, pick, or file the wart immediately before treatment unless instructed. Keep the treated area clean and protected as directed. Do not share towels, nail tools, or footwear, and wash hands after touching the lesion because wart viruses can spread to nearby skin. A dressing may be needed while the surface is tender. Ask whether [Wart Removal](/treatments/surgical-dermatology/wart-removal/) or [Imiquimod Treatment](/treatments/medical-dermatology/imiquimod-therapy/) better fits the location and type of wart.

Call the clinic if pain, warmth, redness, drainage, or swelling keeps increasing, or if you develop fever. Seek prompt assessment for bleeding that does not settle with firm pressure. A lesion that rapidly changes, repeatedly returns, or fails to behave like a typical wart needs reassessment rather than repeated self-treatment.

How confident are we that this is a wart? Why is laser suitable for its location? What wound care is needed, and how can I reduce spread to family members or other body sites?
