A needle biopsy is the removal of cells or a small piece of tissue with a needle. A needle biopsy most often uses a thin, hollow needle put through your child’s skin into his or her body. A core needle biopsy uses a larger hollow needle to remove a solid piece of tissue.
Needle biopsies may be used to help diagnose infections, cancer, and other diseases.
The biopsy may be done at your provider's office, an outpatient clinic, or the hospital.
Your child will be given medicine called anesthesia to keep him from feeling pain during the procedure. Local anesthesia numbs part of the body where your child will have the procedure. General anesthesia relaxes the muscles and puts your child into a deep sleep.
Your child’s provider may use a CT or ultrasound scan to find the exact location of the tissue to be biopsied. The healthcare provider will insert a needle into the area to remove cells or tissue. The cells or tissue will be sent to the lab for tests. The provider may put a small bandage over the area where the needle went through your child’s skin.
Your child may have some swelling or bruising in the area of the biopsy. Follow your healthcare provider's instructions. Ask your healthcare provider:
Make sure you know when your child should come back for a checkup. Keep all appointments for provider visits or tests.
