Wart removal can also be done by a podiatrist or in clinics or hospitals, but this is less common and is usually reserved for the most difficult cases of warts. Warts are contagious and can spread to other parts of your body, as well as other family members and people that you come in contact with. For this reason, it is important to treat warts as soon as they appear. It is also easier to eliminate young warts than those that are already established.
