There *are* docs here (internal medicine, gp, family practice, surgeon)
who have bf their children.  Would one of these be a better choice?  The
surgeon?

Question:  *Is* calcification of the milk ducts a possibility for a
long-term bf mom?  Should she pursue a biopsy?

Calcification on the mammogram is one of the hallmarks looked at on the mammogram as a sign of cancer.  Since this is a baseline study she has no prior films to compare to.  Most doctors regardless of there BF friendly quotient are going to tend to be on the side of aggressive when it comes to calcifications on the mammogram because of the high litigation risk for failure to treat/diagnosis for Breast Cancer.  Depending on the appearance of her mammogram, she might be a candidate for a sterotatic core biopsy of the suspicious area of the breast.  This is an outpatient procedure that is done with the patient awake, using local anesthesia.  It is possible to do a mammogram on the core sample taken, (about the diameter of a pencil lead) to make sure that the suspicious calcification is removed on the core biopsy sample.  This is a different procedure than needle aspiration.  Make sure that the doctor you are talking with know that you are not referring to this needle aspiration procedure.  This stereotatic procedure isn't done everywhere, but is becoming more popular due to the decreased cost (outpatient) and risk ( no anesthesia) and less scaring ( a 14 gauge needle puncture instead of an incision).  The risk is that the core biopsy can still damage ductile structures ( though probably less so than an incision) and that the core biopsy can be a false negative and miss the cancerous cells.
