Hi @R_STAR,
I was ER+, PR+, HER2- and grade 3. My Ki factor was 69 so high chance of return. I had a lumpectomy and radium and chemo.
Grade 3 usually means fast growing irregular cells so a bit more aggressive cell growth than a grade 1 cell.
Radium is usually done for women who keep their breast and chemo is dependent on a range of factors eg that ki factor is one whether it's in the lymph etc
Unfortunately with cancer while we want certainty we just have to wait until the drs get all the information and the pathology is critical to deciding the course of treatment.
The best approach to this is one step at a time and not getting too far ahead of yourself. For now keep busy and focus just on the surgery. You'll get the rest of the plan when the drs have all the information to recommend the way forward for you. Best wishes
