How does a wart look like? Plantar warts and palmer warts are noncancerous skin growths, caused by a viral infection in the top layer of the skin. The culprit is a strain of virus called human papillomavirus or HPV. Many strains of the virus exist, and those that cause common warts on the hands and feet are not the same strains of HPV that cause genital warts.
Some people mistakenly think plantar warts or palmer warts are malignant. In fact, they are not harmful. Eventually, in about two years, most warts go away without treatment. Warts can, however, cause irritation or minor pain, depending on their location. Also, warts may appear unsightly and make the person who has them self-conscious.
