For small biopsies and fine-needle aspirations, the results may be available the next day. The results of most breast biopsies will be available within a few days. Sometimes special testing must be performed, and the results may be delayed and take longer. This does not necessarily mean that a cancer is present. For example, sometimes the tissue sections must be recut to reveal deeper layers of the tissue to allow for optimal evaluation by the pathologist. In other cases, special tissue stains may be necessary to help the pathologist assess the tissue sample under the microscope. The radiologist or surgeon performing the procedure will be able to give you a better idea of the approximate time frame and how the result will be communicated to you.
