Results pre and post surgery how do they differ?

breastquest

I'm interested in knowing how the post lumpectomy pathology report/results may differ from beginning 3d mammograms/biopsy and MRI? In other words, barring margins etc... did anyone get very similar results, or did something become known that was unknown at that point? It seems that some women get different results then all the testing that went before it...

Anyone get similar results? Obviously, surgery pathology reports seem more exact, but just curious.....?

Are you asking about possible IDC with DCIS? Or tumor ER/PR features? I’ve read that something like 20% of the time they might find something nastier in a lumpectomy. As to tumor features, I’m sure they can be different in the final pathology but I would think that’s the exception

when I had my needle biopsy is came back just ADH, but after wide excision, it was upgraded to DCIS.

My DCIS was upgraded to IDC at final pathology. The final size however was smaller than originally estimated by imaging

My DCIS was upgraded to IDC after surgery ...

Biopsy: DCIS, intermediate grade with comedonecrosis, 2.8 cm. MRI said 2.5 cm. Final pathology was DCIS, high grade, 3.2 cm.

Re-excision cleared the margins, and no change in pathology.
