Oncotype results anxiety fears

Getting oncotype results on Wednesday and highly anxious doc will tell us that my wife needs chemo.  Was wondering how much chemo reduces recurrence?  Also she is stage 1 grade 3.  Does grade 3 result in high oncotype score?

I was diagnosed with stage 1 grade 3 breast cancer 8/8 oestrogen positive, my oncotype score came back as 22, that is what they call a grey area meaning it was my choice whether to have chemo or not.  I decided against chemo instead I had 15 days of radiotherapy plus 5 days of booster rads, I have also been on Anastrozole for just over 3 years.  It is a difficult decision to make whether or not to have chemo but the recurrence percentage of 2% for me made me decide not to. I hope all goes well for your wife on Wednesday. 

How did your wife go did she have chemo?

Im waiting on oncotype results on 4th week so scared waiting on call.

Um stage 1 grade 2.

Will be having radiation and hormone tablets .
