Biopsy Difference

What is the difference between a core biopsy and a
stereotactic biopsy? I had the core biopsy and a
previous lumpectomy, and after my recent mammogram
I was told I needed a stereotactic biopsy for a
cluster of calcifications in my other breast.
Thank you.

Dear Scrunch, The difference between the core biopsy and stereotactic biopsy would be in the techniques surrounding the localization of the abnormality. The core biopsy is a type of needle biopsy where a small core of tissue is removed from a lump without surgery. It may be used when there is an actual lump felt and can be targeted.
In stereotactic biopsy, computer-assisted X-rays allow the biopsy needle to be precisely positioned, especially for smaller lumps or lumps that cannot be felt. Special mammogram films are taken of the site to be biopsied. The radiologist uses these films and, with the assistance of a computer, calculates the exact location for needle placement to obtain the biopsy.
The procedure begins with cleansing the skin and applying a local anesthetic to numb the skin surface. The radiologist then introduces a sterile biopsy needle. Additional X-ray films are taken to confirm accurate needle placement. Tissue samples are obtained through the needle. It is standard procedure for the needles to be inserted three to five times in order to obtain an adequate tissue sample, this portion of the procedure takes ten minutes or less. The biopsy site is so small, a Band-Aid is usually all that is applied, and a woman can resume her normal activities after the procedure is completed. The entire procedure takes about one hour.

Hi, I had a double stereotactic biopsy 3 weeks ago. The doctor remarked I had a large hematoma. I understand that it is a blood blister. How long will I have it? It is still large and I haven't felt any difference in it since the day of the biopsy. Thanks.
