My diagnosis was almost exactly the same, the only difference was it was closer to Grade 3 than Grade 2 and my PR+ wasn't too strong. Because of my circumstances (click on my @ name to read my story) my oncologist advised that I have a genomic test. This looks at how likely my cancer was to recur/metastasise. It came back as a clear yes so I had chemotherapy.
We're all different. Our doctors are all different. Don't go by anybody else. Trust your gut, make sure you trust your team, and take things one day at a time.
Deep breaths! And a big hug from me, K xox
