Oh wow you are the first person I have come across with very similar situation. I had DCIS, grade 3, large and hormone negative but left breast - there doesn't seem to be many people with Dcis hormone negative an not much research. I'd love to know what checks your team have recommended post surgery. And interesting that radiation was put on the table I haven't come across this with masectomy in the caseof DCIS - I'm on 6 month check ups now an back in early June at cedars so going to raise the imaging, MRI survelliance again.
