    Reasons for Procedure

    • Lesion is precancerous or cancerous
    • Lesion has created a chronic skin irritation
    • Cosmetic preference

    Possible Complications

    Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
    • Bleeding
    • Scarring
    • Changes in skin color
    • Infection
    • Poor wound healing
    • Nerve damage
    • Recurrence of the lesion
    Some factors that may increase the risk of complications include:
    • Smoking
    • Suppressed immune system
    • Bleeding disorders
    • Circulatory problems

    What to Expect

    Prior to Procedure

    Generally, no special preparation is required.


    Local anesthesia will be used. It will make the area numb.

    Description of the Procedure

    The area will be cleaned. The skin surrounding the lesion will be numbed by anesthesia. Techniques for skin lesion removal vary depending on the reason for removal and lesion location. Common techniques include:
    • Removal with scalpel—The lesion is cut away with a surgical knife.
    • Laser surgery—A high-energy beam destroys skin tissue.
    • Electrosurgery—This is the use of an electrical current to selectively destroy skin tissue.
    • Cryosurgery—A cold liquid or instrument is used to freeze and remove the lesion.
    • Curettage—This is the scraping of the skin with a circular cutting loop instrument.
    • Mohs micrographic surgery—This is used to examine suspected cancerous lesions. Small pieces of tissue are successively removed and then viewed microscopically for signs of cancer. The goal is to get all the cancer tissue and leave as much healthy tissue as possible.
    After the lesion is removed, stitches will be used to close the hole left in the skin. Clean stickers may also be used to help keep the skin closed. A bandage will be placed over the area.

    How Long Will It Take?

    This depends on which procedure is used. Most are completed within 20 minutes.

    Will It Hurt?

    Anesthesia prevents pain during the procedure. You may have some discomfort at the surgery site after the procedure.

    Post-procedure Care

    When you get home:
    • Keep the area clean and dry. Keep it covered with a sterile bandage for 1-2 days. If stickers were placed, they will fall off on their own in about a week.
    • Take pain medication if necessary.
    • Follow any special care instructions to prevent infection.
    Stitches will be left in the skin for 3-14 days, depending on where they are located.

    Call Your Doctor

    It is important to monitor your recovery. Alert your doctor to any problems. If any of the following occur, call your doctor:
    • Signs of infection, including fever and chills
    • Redness, swelling, increasing pain, excessive bleeding, or discharge from the incision site
    • Pain that you cannot control with the medications you were given
    • New or unexpected symptoms
    If you think you have an emergency, call for emergency medical services right away.
