clustered Microcalcifications

My wife had a biopsy 2 tears ago on her left breast to evaluate clustered microcalcifications. The Biopsy revealed there was no malignant cells detected. There were indications of microcalcifacations detected in the right breast at that time but they were not clustered. The next years mamograph indicated no changes in either breast. This years Mamograph shows the microcalcifications in the right breast are clustered. should she have a right breast biopsy.   At what point if any would a person stop having a biopsy when these clusters are there. Or should she keep having a biopsy just to be safe.

Dear jmnitsua,  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.  The decision of whether or not to biopsy would be based on the appearance of the abnormality, comparisons to prior films etc.   Her breast surgeon would be best able to advise regarding whether or not a biopsy was appropriate this time based on review of her films, comparisons to prior films etc.
