Moles occur when cells in the skin grow in a cluster instead of being spread throughout the skin. Most moles are not dangerous. Moles that are more likely to be cancer are those that look different than other existing moles. If you notice a change in color, height, size, or shape, or if they bleed, ooze, itch, or become tender or painful, you should schedule an evaluation appointment with a dermatologist.
Warts are viral clusters that appear on the skin.
Moles and warts can be treated by freezing (cryosurgery), scraping & burning, surgical removal (excision), and laser surgery.
