Then what causes the cancer if its not the mirocalcification?
Dear vicki53: Microcalcifications are very fine specks of calcium that light up on a mammogram. Sometimes they can be an indication of cancer or precancer. Based on their pattern on the mammogram it gives the radiologist clues as to their cause. For instance microcalcifications that are more scattered are probably due to benign (non-cancerous) causes (such as normal wear and tear on the tissue), a “cluster” of microcalcifications may increase concern that there may be an underlying tumor. In these cases, biopsy is generally recommended. Microcalcifications do not "turn into" cancer.
