Warts usually disappear within a year or two and are little more than an inconvenience. But because they shed virus particles into the surrounding area, they are contagious and can cause new warts to appear nearby. In some people, warts may be a more chronic (long-lasting) problem. These people may have individual warts that won't go away or they keep getting new warts. Warts that continue to persist or grow despite treatment should be examined by your doctor since some skin cancers can masquerade as warts.
