A wart is a small, benign growth on the skin caused by the human papillomavirus (HPV). Warts can appear anywhere on the body but are most commonly found on the hands, feet, and face. They often have a rough texture and can vary in color, typically appearing as skin-colored or slightly darker. Warts are contagious and can spread through direct contact or by touching surfaces contaminated with the virus. While they are generally harmless, some people may choose to remove them for cosmetic reasons or if they cause discomfort. Treatment options include over-the-counter medications, cryotherapy, and laser therapy.
