Needle biopsy of the breast

   

A needle biopsy is performed under local anesthesia. Simple aspirations are performed with a small gauge needle to attempt to draw fluid from lumps that are thought to be cysts. Fine needle biopsy uses a larger needle to make multiple passes through a lump, drawing out tissue and fluid. Withdrawn fluid and tissue is further evaluated to determine if there are cancerous cells present.
