What is the difference between a mole and a wart?

A mole is a common skin growth that typically appears as a small, dark spot and is made up of clusters of pigment-producing cells called melanocytes. Warts, on the other hand, are benign growths caused by human papillomavirus (HPV) infection and often have a rough texture. While moles are generally stable and can vary in color, warts can be more variable in appearance and may spread through skin contact. Both are generally harmless but may require medical evaluation if they change in appearance.
