How is an excision biopsy of the breast done?

An excision (surgical) biopsy can also be done in different ways:

• Surgical biopsy of palpable growths (lumpectomy): This procedure removes part or all of a breast growth, or lump. The doctor makes an incision one or two inches (about 2.5 to 5 cm) across and removes the sample. If the lump is small and measures an inch (2.5 cm) or less across, the doctor usually removes the entire lump for testing. If the lump is large, the doctor usually removes only a portion of it for testing. If cancer is found, the rest of the lump can be removed at the time of the biopsy or at a later time.

The doctor closes the opening with sutures or clips which remain in place for about a week. Patients who receive general anesthesia rather than a local will require about an hour to recover from drowsiness after the surgery.

• Surgical biopsy for non-palpable lumps: This procedure is similar to lumpectomy except that the growth is first located by mammography or other imaging studies and then "marked." The doctor inserts a needle that conveys a wire with a hook on the end into the breast, all the while using the image as a guide. After anchoring the hooked wire to the lump, the doctor withdraws the needle and performs the surgery. Another option is to inject a dye to mark the spot rather than using a hooked wire.

What is the time frame for receiving the results of a breast biopsy?

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 take a bit longer. The radiologist or surgeon performing the procedure will be able to give you and idea of the approximate time frame that the result will be available. Your physician should also let you know how the result will be communicated to you.
