@prc73 it would seem,, with the field of calcifications and multi-focal DCIS, you need a mastectomy, right? Then if your lesions are ER+ (estrogen-responsive) and HER2-, which pathology will tell you after surgery, they will do an Oncotype test to determine treatment.

I had what seemed like a nasty grade 3 invasive cancer but did not have chemo or radiation. The Oncotype guided my treatment after mastectomy (my choice) and I did hormonal meds for 5 years.
