Fine-needle Breast Biopsy


Fine needle breast biopsy is a procedure to find the cause of a breast lump. This procedure uses a small needle to collect fluid or cells from your breast. The samples are then sent to a lab and examined for cancer.


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 is medicine used to numb an area of your body that will have surgery or a procedure. The medicine may be given in an injection, cream, gel, or patch.

During your procedure:

Your healthcare provider will insert a needle into your breast where the lump was found. The needle is attached to a syringe. Your healthcare provider may need to get more than one sample. X-rays with a monitor or ultrasound may be used to locate the tissue or lump. When the needle reaches the lump, fluid or cells are sucked out into the syringe. The samples collected will then be sent to a lab for tests.

After your procedure:

A small bandage may be placed over the spot where the needle went into your breast. You will then be allowed to go home.


You may have bruising or discomfort in the area where the biopsy was done. You may bleed more than usual or get an infection. If you do not have the breast biopsy, you may have cancer and not know it.


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.
