I had a biopsy under ultrasound last week as they found a micro calcification cluster in right breast, area size 20mm. Reported M3. I am freaking out as I have a 1 year old and 4 year old and so scared of anything happening to me. I don't get the results for another 6 days, and I have so many questions. Does know if this area is large for a cluster and if that indicates anything? I can't find anything online. Apparently it's in a milk duct, but milk ducts are not that large so now freaking out that it's spread outside of cancerous. 
 

Any information anyone has would be gratefully received.
