Warts are small growths on one’s skin that do not result in any pain. Some normally hurt or itch. There are five types of warts, i.e., genital warts, plantar warts, common warts, flat warts and periungual or sublingual warts. They are caused by HPV virus. They are contagious and can be spread via direct contact. Warts in the skin can be removed by applying cantharidin or salicylic acid. They can also be removed by simply cutting them off or using laser and cryotherapy to remove.
