12/27/2017I had a lumpectomy on may 2016 followed by 19 radiations was stage o going in and coming out after surgery. am on tamoxifen. I had a six month mammogram and just this month of December 2017 had a yearly mammogram. Impression: New calcifications at lumpectomy site-superolaterally. was told these may represent fat necrosis but would not exclude malignancy. am scheduled for other sterotatactic needle core biopsy to check breast calcifations I was diagnosed with dcis in April 2016! ACR BI-RADS CATEGORY 4 SUSPICIOUS--LETTER SENT SAYS ABNORMAL EXAM. EXAGGERATED CC. BREAST TISSYE IS HETEROGNEEOUSLY DENSE which could obscure detection of small masses. findings were expected post lumpectomy changes in breast with fat necrosis oil cysts at lumpectomy site superolaterally in the anterior of breast. There are now present new microcalcifications at the lumpectomy site spanning a distance of 2 cm. morphologically these are heterogeneous in appearance and indeterminate as to probability of malignancy. since I am on tamoxifen and the person reading the mammograms is making sure of findings-he seems to lean toward fat necrosis in surgical area with much scar tissue! Just confused but hopeful--no other problems noted! Needle core biopsies are painful and I guess this is the only way to have a true diagnosis of the area. My oncologist office said problem would be rare since I am on tamoxifen! So confused!

12/27/2017when the lumpectomy was done, it hopefully included getting margins in all 6 directions of at least 2mms for all margins. that would reduce the probability of this being a local recurrence. we hope too this is just fat necrosis. no way to guess further. inquire if calcs are pleomorphic because if they are this may up the risk of being a local recurrence.
