Punctate Pleomorphic Calcifications

Had diagnostic mammogram recently.  All previous were Normal w/multiple cysts. Now have reading of Indeterminate lt breast calcifications, (behind Nipple) "Cluster of punctate pleomorphic microcalcifications seen in the anterior third of left breast laterally at 3 O'clock position. There is suggestion of some architectural distoration of the breast tissue in this area and perhaps a tiny mass.  Remainder of breast tissue is normal" Hx. Mother with Breast CA at 43.  I had breast augmentation 10 years ago.  I'm scheduled for Stereotactic Core Biopsy tomorrow.
How shall I interpret these findings.  Does pleomorphic description had greater risk of cancer findings.  Will a stereotopic Core Biopy be the best dignostic tool.  Will the implants be in jeapody during Biopsy?

Dear perfuse:  Microcalcifications are small calcium deposits found within the breast tissue. Microcalcifications in and of themselves are not a condition that would become cancerous however they can be a sign of a problem that may need further investigation based on their appearance on a mammogram.  For instance microcalcifications that are more scattered are probably due to a benign (non-cancerous) cause, a “cluster” of microcalcifications may increase concern that there may be an underlying tumor, thus the recommendation for further testing which may include a biopsy.  

The best type of biopsy is a judgement made by the radiologist based on what he/she sees on the films and the probability that a good sample can be obtained.  The implants would be considered in this approach.  Of course, a complication can always occur with any procedure but the biopsy should be able to spare the implants.
