Patient Instructions - Needle Biopsy

A needle biopsy is a procedure in which a needle is inserted through the skin into an organ or abnormal lump or mass inside the body to obtain a sample of tissue. The biopsy is done to assist your physician in identifying the cause of abnormal organ function or the cause or an abnormal lump or mass somewhere in the body.

Before your Procedure

  • Certain medications may increase your risk of bleeding and may need to be held prior to your procedure. You may resume these medications the day after your procedure unless otherwise instructed.

  • Do not eat or drink anything after midnight the night before the biopsy.

During your Procedure

  • A radiologist will use ultrasound or CT pictures for guidance when selecting the best site for the biopsy.

  • A local anesthetic (numbing medication) will be injected into the area using a small needle. You may feel a burning or stinging sensation as the medication is injected.

  • The biopsy needle is then placed and used to remove a tiny piece of tissue or some cells from the mass. These samples are sent to the laboratory where they will be examined.

  • Length of the procedure is about 1 hour.

After your Procedure

  • Expect to rest and be monitored.
