calcium deposits

Eight years ago I had a masectomy on the right breast due to cancerous deposits in two areas of the breast, and cancer in nine out of twelve lymph nodes which had been removed.  Recently, I had another mammogram in the other breast, which showed calcium deposits, and was told there was one calcium deposit which was different to all the others.  I am to be called back to the hospital in three months, is there a possiblity, that this deposit will be ok or cancerous?

Dear Lizzy541:  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 appearance of a new area of microcalcifications is not uncommon and each occurrence of a new area of microcalcifications would be evaluated separately.
