What does a breast fine needle biopsy feel like?

Minimal pain. A fine needle biopsy is performed with a needle about the same size as is used to draw blood and it hurts only a little bit more. Many surgeons, such as myself, will use local anesthesia to decrease this pain further. Nowadays, it is much more common to have a core needle biopsy, which will give us a lot more information with only a little more discomfort.
Pressure. This procedure is where the physician samples some cells from an area in your breast. There is no incision. The area is numbed with local anesthetic. Then the physician uses a needle attached to a syringe and moves it back and forth several times through the area in your breast.
