What is a common treatment recommended before attempting surgical interventions for a wart?

Salicylic acid therapy is a common first-line treatment for warts due to its effectiveness in gradually removing the wart tissue. This over-the-counter treatment works by softening the wart and promoting peeling of the infected skin. Salicylic acid is a keratolytic agent, meaning it helps to break down the protein (keratin) that makes up the wart and the thick skin surrounding it, allowing for easier removal. This approach is non-invasive and can often lead to significant improvements or complete resolution of the wart before considering more invasive options, such as surgical interventions.

Other treatments mentioned, like electrosurgery and cryotherapy, are typically used after initial therapies have failed, as they are more invasive and carry a higher risk. Topical antibiotics are not relevant for treating warts, as warts are caused by a virus and not a bacterial infection. Thus, salicylic acid therapy serves as an effective and recommended starting point before proceeding to surgical options.
