calcification

Could any one tell me what percentage of people who get breast cancer from microcalcification? Or maybe how often does it turn into cancer.Thank You

Dear paula914:  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.  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.
