Cryotherapy Wart Removal


Cryotherapy wart removal is a procedure to remove your wart by freezing it. This is done using a cryogen (freezing chemical), usually liquid nitrogen.


Before your procedure:

  • Informed consent is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.
  • Local anesthesia: This medicine is used to make you more comfortable during your treatment. It can be given through a shot or put directly on your skin. It is used to numb the area and dull your pain.

During your procedure:

Your caregiver will numb your skin and remove any dead skin on your wart. He will then use a cotton swab, spray, or cryoprobe (long, pointed device) to apply the cryogen to your wart. It may take up to 60 seconds for the wart to freeze. The frozen tissue will then be allowed to thaw slowly. A second application may be applied after a few minutes. How long the treatment takes will depend on the size of your wart and the skin area being treated.

After your procedure:

You may see a small ring of ice around your wart. Your caregiver may cover it with a bandage to keep it clean and dry. When the procedure is over, you may be able to go home. You may have pain in the treated area after the procedure. In a few weeks, the dead wart tissue may dry up and fall off.


Cryotherapy may be painful and cause blisters, scarring, or an open sore at the treatment area. The part of your skin that was treated may darken or lighten. Even after the procedure, the wart may not completely go away or may come back. Sometimes, treatment of genital warts may cause pain that does not go away. Without treatment, your wart may grow in size or number and become painful or bleed. The wart may spread to other parts of your body. Genital warts may cause problems with having sex and you may pass it on to another person.


You have the right to help plan your care. Learn about your health condition and how it may be treated. Discuss treatment options with your caregivers to decide what care you want to receive. You always have the right to refuse treatment.
