Warts

Understanding Warts: Causes, Types, and Effective Treatments


Warts are non-cancerous skin growths caused by the human papillomavirus (HPV), which infects the top layer of the skin. These growths are characterized by small, raised bumps on the skin’s surface that can vary in appearance—from smooth and flat to rough and cauliflower-like. Warts can appear anywhere on the body but are most commonly found on the hands, feet, and face.

Warts are highly contagious and can spread through direct contact with an infected person or surface. They may also spread from one part of the body to another through scratching or touching. While warts are generally harmless, they can be bothersome, painful, or aesthetically displeasing, prompting many individuals to seek treatment.
