Core Needle Breast Biopsy
A core needle breast biopsy is a diagnostic procedure used to assess a lump found in the breast for possible pathology. Less invasive than a surgical biopsy, a core needle biopsy allows a doctor to remove samples of cells and fluid through a small incision.
The patient lies on her back on a table while the physician locates the abnormality on an ultrasound, and then makes a mark in pen on the skin to indicate where the needle should be inserted. The skin is sterilized and numbed with local anesthetic. A small incision is made in the skin, and the needle is inserted.
The physician either aims the needle directly at the area of the lump, sometimes using an imaging technique, such as a handheld ultrasound transducer, to confirm the precise site of the perceived abnormality. Cells and fluid are removed from the area and sent to a pathology lab for testing and results are usually available within 24 to 48 hours.
Patients who take aspirin, blood thinners or anti-inflammatory medication regularly should stop a few days prior to the biopsy as recommended by the physician. Strenuous activity should be avoided for 24 hours.Any minimal post-biopsy discomfort can be managed with Tylenol.
