Large Core Biopsy

Dr wants to remove abnormal cells from breast using large core biopsy technique. 1. Is this better than the open surgery way?  I have read that large core biopsy unnecessarily removes healthy tissue in order to get to the abnormal cells.  2.  Dr wants me to have general anesthesia because of the cosmetic work she may have to do.  Is this OK?  I read that this procedure can be performed with local.

Surgery is this Friday.  Thank you so much for your time.

Dear Merryl:  The type of biopsy that is recommended depends upon the abnormality, how it is best visualized, and the method believed to give the best information, minimizing any other tissue damage.  A large core biopsy technique generally uses a large core needle and a special mammogram to visualize the abnormality.  The needle is inserted and tissue obtained for analysis.  There is not usually a need for general anesthesia or cosmetic work with this procedure.  An excisional biopsy, on the other hand, removes the entire area of tissue that is of concern.  This procedure removes considerably more tissue and may require some cosmetic work.  You may want to clarify the recommended procedure with your doctor.  If you are not comfortable with the discussion, consider a second opinion.
