Breast Calicifactions

My Mammo report read that I have increased "branching" calicifactions and suggests a biopsy.  Does anyone know what that means?

Dear SharonLynn:  Microcalcifications are small calcium deposits found within the breast tissue and these are normal. 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 and microcalcificatins that form a cluster may increase concern that there may be an underlying tumor.  Microcalcifications that are indeterminate may need further investigation such as a diagnostic mammogram to further characterize the calcifications.  Branching is not a technical term but probably a descriptor used by the radiologist to describe a pattern.  Calcifications do not move around but more may form over time.  The pattern of their formation lends clues as to whether or not more investigation is needed.
