• Biopsy


    A biopsy is the removal of a sample of tissue or cells. The sample is examined under a microscope.
    A biopsy may be taken from any part of the body.

    Reasons for Procedure

    A biopsy is used to see if the cells from a sample of tissue are abnormal. A biopsy is done to rule out cancer and/or to specify its type and level of aggressiveness.
    Biopsies are sometimes taken to find out the cause of an unexplained:
    • Infection
    • Swelling
    • Growth
    Common interpretations of biopsies include:
    • Normal tissue, no abnormalities
    • Irritated tissue
    • Not normal, but difficult to interpret
    • Not normal, not cancerous, but a precancerous condition
    • Cancer
    • Inconclusive

    Possible Complications

    Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
    • Excessive bleeding
    • Pain
    • Infection
    • Scarring
    • Results that are difficult to interpret
    Smoking may increase the risk of complications.
    Be sure to discuss these risks with your doctor before the surgery.

    What to Expect

    Prior to Procedure

    Talk to your doctor about your medication. You may be asked to stop taking some medications up to one week before the procedure.
    Avoid eating or drinking after midnight if you are going to have general anesthesia.


    The type of anesthesia used depends on what you are having biopsied:
    • General anesthesia is given through an IV to block pain and keep you asleep through the procedure.
    • Local anesthesia is given as an injection to numb the area being operated on.

    Description of the Procedure

    For a simple biopsy, the area will be cleaned. A numbing medication will be injected into the area so that you will not feel pain. A piece of tissue will then be removed. The opening may need to be closed.
    The procedure that your doctor uses will depend on the type of biopsy that you are having. For example:
    • Needle biopsy —cells are removed using a thin needle
    • Aspiration biopsy —cells are drawn out with a hollow needle that uses suction
    • Core needle biopsy —a sample of tissue is removed using a hollow core needle that has a special cutting edge
    • Vacuum-assisted biopsy —a number of samples of tissue are taken using a special rotating probe
    • Endoscopic biopsy —the area is viewed with a long, thin tube that has a lighted camera on one end; a tool is passed through the tube to take the biopsy sample
    • Incisional biopsy —a portion of a mass is removed by cutting it out
    • Excisional biopsy —a mass is completely removed, such as a breast lump
    • Punch biopsy —a core of skin is removed with a special biopsy tool
    • Skin biopsy —a small piece of skin is cut off with a scalpel
    • Shave biopsy —top layers of skin are shaved off with a special blade
    • Bone marrow biopsy —a long needle is inserted into the bone marrow to collect cells

    How Long Will It Take?

    A simple biopsy usually takes a few minutes. A biopsy involving surgery takes longer.

    How Much Will It Hurt?

    You may have pain in the area where the sample was removed. Ask your doctor about medication to help with the pain.

    Average Hospital Stay

    You will be able to go home after a simple biopsy. If your biopsy involved surgery, you may need to stay in the hospital for 1-2 days.

    Post-procedure Care

    Be sure to follow your doctor's instructions on wound care to avoid infection. If you have stitches, have them removed when instructed.

    Call Your Doctor

    Contact your doctor if your recovery is not progressing as expected or you develop complications, such as:
    • Redness, swelling, increasing pain, excessive bleeding, or discharge from the biopsy site
    • Signs of infection, including fever and chills
    • Pain that you cannot control with the medication you have been given
    • New or worsening symptoms
    If you think you have an emergency, call for emergency medical services right away.
