I heard it's not possible. Personally I had an outbreak of warts a few years ago and when I heard it cost over $2000 to get rid of them I snipped them off with a sterile blade and used Colloidal Silver and goldenseal with hydrogen peroxide. I thought I had one coming back during my time of extreme stress last year but it didn't surface.
personally I believe that it doesn't really go away but can be kept at bay with healthy living. As long as it stays away from my cervix!
