Laser Surgery for Warts

Laser surgery uses an intense beam of light, or laser, to burn and destroy the wart tissue. It is usually done in a doctor's office or clinic. Local or general anesthetic may be used, depending on the number of warts to be removed or the size of the area to be treated.

What To Expect After Surgery

The wound will be painful for a few days after laser surgery. Recovery time depends on the location and number of warts removed.

After laser surgery, call your doctor if you have:

  • Bleeding that lasts longer than 1 week.
  • A fever.
  • Severe pain.
  • Bad-smelling or yellowish discharge, which may mean an infection. Cleaning the wound area helps prevent infection.

Why It Is Done

Laser surgery may be considered when:

  • Medicine has failed, and it is necessary to remove the warts.
  • Warts are large or widespread.
  • Warts need to be treated during pregnancy. Your doctor will recommend when treatment should be done during pregnancy.

How Well It Works

Laser surgery may help when other treatments don't work, but it doesn't seem to work better than cryosurgery or electrosurgery.1

Risks

There is a slight risk of infection associated with laser surgery. Signs of infection include:

  • Increased pain, swelling, redness, tenderness, or heat.
  • Red streaks extending from the area.
  • Discharge of pus.
  • Fever of 100°F (38°C) or higher with no other cause.

What To Think About

Laser surgery:

  • Normally causes no scarring.
  • Requires local anesthetic.
  • Is more expensive than most other methods of wart removal.
  • Is not recommended as an initial treatment.
  • Is usually used for large, hard-to-cure warts.
