Warts
These skin lesions are caused by the human papilloma virus (HPV). They are not dangerous but are contagious, spreading to other areas of the skin and to other people.
Your own immune system may clear your warts, without treatment being needed. Unfortunately, however, it is not uncommon for warts to persist well beyond a few months. When treatment is required, a number of options exist.
Cryotherapy, using liquid nitrogen to freeze off the warts, is fast and healing is quick. The virus is then destroyed by your body’s immune system. Topical treatments can be helpful. They include blister-causing chemicals and some allergic-causing chemicals, applied to the wart to inflame and eventually destroy it. Over 30 treatment options exist, and your dermatologist will tailor your treatment plan individually to you, guided by your age and the number, type, and location of your warts.
