Prior breast cancer current mammo requires biopsy because of clusters

My six month mammogram, after three years of being cancer free (after lumpectomy, chemo and radiation) my family Dr. says shows clusters and they want to do a biopsy.  What kind or kinds of clusters would this be?  My Mother died with breast cancer and I have a sister who is seven years cancer-free of breast cancer after the same treatments I had.  My lymph nodes were all clear on the first surgery.


This discussion is related to Cluster of Lumps.

The "clusters" they are talking about are a cluster or grouping of Microcalcifications that indicate there may be an underlying condition. These calcifications that appear as tiny dots on film are seen normally scattered about within the breast tissue. When they are observed in groups or clusters there is a need for further investigation. This does not necessarily mean cancer ... many biopsies come back as benign. This doesn't have to be related to your previous cancer in any way but definitely needs to be investigated to some conclusion.   Regards ....
