Warts are caused by the HPV virus and therefore belong to infectious diseases. Treatment of warts is sometimes very difficult, and depends on the type, number, size and location of the warts. As for treatment options, in addition to liquid nitrogen, warts can also be removed after local death with an electric needle, laser, or surgery. Various wart softening preparations (preparations containing salicylic acid) are also used in the treatment. In the case of a larger number of warts and neoplasms, an examination of the immune system, which may show certain disorders, should also be considered. In that case, we can also prescribe general therapy to support immunity.
