stock_7.jpgWarts are the result of a virus that causes many cells to grow on the external layer of skin. They are typically skin-colored and tough, but sometimes they are dark brown, flat and/or smooth. Warts are not dangerous to your health or cancerous, and they usually fade away on their own over time. Typically found on your hands and feet, common warts can make patients feel self-conscious and want them removed. Removing the warts will keep them from spreading, but they might come back as they can be a recurring problem.
