microcalcifications follow up 6 months

I am 41 and had my first screening mammogram.  The report indicated multiple microcalcifications, which appeared "morphologically benign"  a six month follow up was suggested beacuse there were no old films to compare.  How worried should I be?  Are microcalcifications common?

Microcalcifications do occur normally in breast tissue. When they are seen in groups or certain patterns there is cause for concern and further investigation is recommended. Evidently since a 6 mo. follow-up was recommended there was no particular pattern seen on mammography. DO follow the recommendation for follow-up though.
