Biopsy

If a tumor is found on imaging, you may need a biopsy. A biopsy is the only way to confirm breast cancer. A biopsy is the removal of tissue to examine cells. Your biopsy may be done by a surgeon or radiologist.

There are different types of biopsies:

Fine needle aspiration (FNA) biopsy: A small needle is inserted into the tumor site or lymph nodes to remove cells. The sample is sent to a pathologist. A pathologist is a doctor trained in looking at cells to find disease. There is no fasting or special preparation needed for an FNA. FNA is almost always done in the doctor's office. It causes little pain. FNA may not always give your team all the information they need. More testing may be needed.

Core needle biopsy (CNB): A larger needle is used to remove a larger sample of tissue and cells. Local anesthesia is used to numb the area. A small cut is made in the skin and then the needle is placed. Tissue is taken from each breast mass to make sure enough cells are checked. Ultrasound is often used to guide the core needle biopsy.

Stereotactic biopsy: Uses mammography to find the exact location of a breast mass. Digital X-rays are taken from two different angles. You will be positioned to place your breast into the opening in the table. You may need to sit in a special chair or lie face down on a moveable exam table. A local anesthetic will be used to numb the area. A clip may also be placed to mark the area in the breast for future treatment and imaging.

Sentinel lymph node biopsy (SLNB): A surgical procedure that removes the first lymph nodes receiving lymph drainage from the tumor. See Sentinel Lymph Node Biopsy.

Keeping You Informed

You may have more testing and imaging before surgery. This helps the surgical team to know your specific type of breast cancer and tailor your treatment to your needs. Your medical history and current physical status will be reviewed as part of the treatment plan.
