Biopsies and Procedures

Fine Needle Aspiration Biopsy

Fine needle aspiration uses a needle to remove tissue or fluid from a lump or cyst in the breast. The sample is then analyzed under a microscope to check for signs of disease.

Simple aspirations attempt to draw fluid from lumps that may be cysts using a small gauge needle. Fine needle biopsy uses a larger needle to make multiple passes through a lump, drawing out tissue and fluid. This screening test does not require any incisions.

Stereotactic and Core Biopsies

A stereotactic breast biopsy identifies the location of an abnormal area in three dimensions using a special mammography machine. The 3D image helps guide a radiologist when collecting a tissue sample for a core biopsy. This technique provides an alternative to surgical methods for diagnosing a breast condition.

Tumor Localization

Tumor localizations mark the surgical site for a breast surgeon. With the guidance of mammography or ultrasound, the breast area is numbered. Then, a thin wire is inserted into the breast and blue dye is injected. When the patient goes to surgery, the markings provide a guided map for the breast surgeon to remove tissue.

Ultrasound Core Biopsies

Your doctor may recommend an image-guided biopsy if you have an abnormal area in the breast that is difficult to locate by feel. With ultrasound core biopsies, a radiologist uses ultrasound techniques to find the suspicious area. Then, a needle is inserted into the mass so tissue can be removed and examined for the presence of cancer cells.
