Greetings. There are many treatment options for a wart and it depends on the location, size and number of warts. The Dermatologist will suggest a treatment option taking into considerations the various factors and accounting for merits and demerits of each procedure. Warts may recur after a treatment and you need to repeat the treatment. A higher dose of zinc helps to prevent a relapse. It is a contagious skin condition and treatment should not be delayed as there is risk of spread to self and others.
