Warts are common skin growths caused by human papillomavirus (HPV) that can develop anywhere on the body through direct skin contact. They most often appear as small, rough bumps on the hands and feet of children and young adults. While most warts resolve on their own within a few years, treatment options aim to remove or destroy warts and include cryotherapy, salicylic acid, imiquimod cream, laser removal, or homeopathic medicines depending on wart type and location.
