What is the treatment to remove a wart from a finger?

To remove a wart from a finger, at-home remedies such as salicylic acid treatment and a pumice stone can be used, according to WebMD. If the wart persists after a couple of months, the patient may want to seek help from a dermatologist.

A dermatologist has many options for wart removal, including freezing or burning off the wart, using a laser, applying a topical medicine called cantharidin, surgical removal, or using medication to enhance the immune system's response to the wart, according to WebMD. Cantharidin works by causing the formation of a blister beneath the wart, which allows part of the wart to be removed when the skin over the blister dies.
