Usually the body's immune system clears warts away without any treatment. However, with age, the immune system becomes less effective, so a child's wart will usually disappear quicker than an adult's. It is not unusual for a wart to last several years.
Warts can spread to other areas of the body.
Certain warts, especially genital warts, increase the likelihood of skin and cervical cancer and should be reported to your doctor. Often warts can be treated at home using over the counter products. However, it is best to have your doctor confirm that this new growth is a wart. After that, you may use such products as Duofilm that you may purchase at your pharmacy. However, Duofilm should not be used on warts of the genitals or eyelids.
