What is a biopsy?
A biopsy is a diagnostic procedure in which a sample of living tissue or cells is removed with a tiny needle to be examined by a pathologist, a doctor specially trained in tissue identification. Many types of tissue can be biopsied including skin, bone, organs and other soft tissue. The sample of tissue is usually examined under a microscope to determine if it is healthy or if it shows any kind of disease or abnormality.
A biopsy may be recommended to find out whether a suspicious mass is cancerous (malignant) or non-cancerous (benign). In some cases, it may be the only way to accurately diagnose a lump or swelling. A biopsy can also help to identify whether there is an infection and what is causing it.
How do I prepare?
Do not take Aspirin, Ibuprofen, Advil, Motrin or Aleve for one week prior to your appointment. If you take Coumadin, Plavix or any other blood thinners, you must get approval from your doctor to stop the medication one week prior to your biopsy. Also avoid fish oil and high doses of vitamins (except for prenatals).
On the day of the appointment, do not apply deodorant, perfume, cream, powder or lotion on the breast or underarm areas. If possible, wear a full cup support bra or sports bra for after your exam and either a zipper or button-down top.
Eating and drinking is okay.

What happens during the test?
After registering for your biopsy and changing into a gown if necessary, the receptionist or technologist will bring you to the exam room. Preliminary images may be taken before the biopsy to assist the radiologist.
The radiologist will then come into the room, explain the entire procedure and answer any questions you might have. An MRI, ultrasound, mammography or CT scan will be performed to locate the exact area being biopsied and to help ensure the most precise needle placement.
The skin is then sterilized and often, a local anesthetic is given. A small nick is made in the skin and a thin biopsy needle is placed into the region of interest. A very small sample of tissue is then removed. The surface of the skin will then be cleansed and the technologist or nurse will put a small bandage over the nick. Some biopsy studies require additional images to be taken.
After the exam, post-biopsy instructions will be reviewed with you. Some biopsy exams require a half an hour to an hour of recovery time before leaving the office. The radiologist will be available if you have any further questions.
What happens after the test?
The tissue sample is sent to a lab where it is analyzed by a board certified pathologist. The findings are then sent to us, as well as to your referring doctor. One of our board certified radiologists specializing in interventional radiology reviews the pathology report and dictates a final report which is transcribed, proofread and signed.
The final report is faxed and mailed to your referring doctor within three to five days. Your doctor will read the report and review the findings with you.
