? Chemotherapy

HiTCH​ 

good luck with your decision making. The network folks have already shared some helpful information. In my case the recommendation made to me for my cancer type (HER2 positive, ER+ and PR+) was very strongly for chemotherapy, lumpectomy and  radiation.
After listening to the data from relevant trials I also found it helpful to understand that having chemo might help eliminate cancer cells present in any “distant sites”. 
A big part of my decision was probably more of a gut reaction and to take as big a swing as I could with the available options in my first treatment. 
Wishing you well as you make your decision.
