Your cancer was grade one so wondering if your estrogen score is on the low side, or the progesterone score, to account for the Oncotype not being lower (not that it is high). Is your estrogen score high enough that you feel you can do anti-hormone treatment alone? Your tumor was pretty tiny! I hope others who had lumpectomy with low grade tumors chime in. I had mastectomies to avoid radiation but mine was grade 3 and bigger. That test looks interesting. I hope you can have it! These decisions are so hard.
