(HealthDayNews) -- Warts are caused by a virus that multiplies in the skin and creates whitish-gray bumps on your hands, under your feet, on your face or in your genital area. According to the Health Service Center at the University of Toronto, a strong immune system is key in preventing them in the first place.
If you already have them, there is no cure-all. Some respond to treatments like surgical excision, liquid nitrogen or the application of various acids. But even if the method is successful, there is a 20 percent chance of the wart recurring at the same or another spot. The good news is that within two years, 65 percent of all warts will be gone -- regardless of any treatment.
