chat gpt based on all the information that I have
Lumpectomy (planned surgery)
~85-90%
Current imaging and grade 1 status strongly favor lumpectomy. Most likely scenario.
Minor adjustment to lumpectomy (slightly bigger area removed)
~5-10%
MRI could show tumor is a little larger than expected or extends slightly. Still lumpectomy, same recovery approach.
Mastectomy (full breast removal)
~1-5%
Only if MRI shows tumor is much larger, multifocal, or other rare findings. Low probability given current info.
Chemo needed after surgery
<5%
Unlikely due to grade 1, ER+ status, and clear nodes. Hormone therapy almost certain.
Lymph node involvement found during surgery
Low
Ultrasound clear; unlikely, but sentinel node biopsy will confirm.
