Pathology Outlines - Breast biopsy marking devices
Core needle biopsy uses a hollow needle to remove samples of tissue from the breast. A pathologist studies these samples under a microscope to see if they contain cancer. If they do, more tests will be done to help plan your treatment. Learn about factors that affect your prognosis and treatment. Before the procedure begins, your provider will use a small amount of local anesthetic to numb the skin and breast tissue around the suspicious area. During a core needle biopsy, a clip may be placed inside the breast you cannot feel it to mark the location of the lump.
