Hi Dr I have few anal warts inside and outside anus. Recently, my Dr has started my treatment with Podowart + oral zinc tablet. Before starting the treatment, I have seen the decrease in the size of one of my anal warts. Is this common, the shrinking of warts without any treatment? Also, my doctor is not gonna apply podowart inside my anus, so wht are the options I can go with to clear internal warts? Also, will these warts, lead to anal cancer in the near future?
