A breast core biopsy is done after an abnormality is discovered in your breast. It is the only way to tell if the abnormality is cancerous. It is also good news that many biopsies can be done through the core biopsy method, a non-surgical procedure. Core biopsies require only local anesthetic and can be done in an outpatient setting. Recovery is quicker and less painful with less scarring.
Costs are also much lower than with traditional surgical biopsies.
For these reasons, many patients and providers prefer core biopsies. A core biopsy is not always the best solution, however. Depending on the extent and position of the abnormality, your physician may recommend a surgical biopsy. Open surgical biopsies often require a two-step procedure. The wire inserted into the breast by the radiologist helps guide the surgeon to the abnormal area.
