Warts are caused by a virus, which makes cells grow rapidly. Warts can also spread, because when part of one dies, it sloughs off and carries the virus to other parts of the body.
Lasers are effective at eliminating warts. A laser is a concentrated beam of light that can destroy warts without cutting, burning or freezing them.
Warts are hard to remove even with surgery, because they often grow back. But the Nd:YAG long pulse laser is able to destroy warts in one or two treatments. The laser doesn’t affect the skin surrounding the wart, but attacks the blood supply that feeds it so that it’s unable to survive.
The Nd:YAG long pulse laser works well even on plantar warts, which can be painful and very hard to eliminate. Plantar warts grow on the bottom of the foot. They can be large, or grow in clusters. The long pulse laser delivers heat slowly to the blood vessels of the wart, taking time enough to destroy the blood supply.
People who have stubborn warts that have grown back are good candidates for laser wart removal. People who have large or multiple warts are also candidates. Sometimes patients who are pregnant have laser wart removal, when medicines and surgery are not advisable.
Laser treatment can be done with a local anesthetic, and there’s no bleeding or lasting soreness afterward.
