code 4 microcalcifications

I just got a follow up mamogram (mammogram) done and got a result "code 4" microcalcifications, increasing in number. The radiologist recommends a biospy to be done. My mom died of breast cancer 2 months ago and I am very anxious about all that. I would like to know the probability of these microcalcifications to indicate cancer.

Dear bellab:  Microcalcifications are quite normal in breast tissue and they are not harmful.  However, microcalcifications that grow in a cluster are suspicious because they sometimes cluster around a mass.  In other words, while the mass may not be visualized on film, a cluster of microcalcifications may indicate that there is abnormal growth in the area.  It is proper in most cases to biopsy the area of microcalcifications.  This would most likely be done with mammography guidance.  A first degree relative, such as your mother, does increase your risk for breast cancer, so I am sure your doctors want to take no risks in your cases.  The only way to determine if there is any cancer is to biopsy.  It is impossible to say, without reviewing your mammogram and performing a biopsy, whether your microcalcifications indicate cancer.
