@jussnunu many of us have avoided chemo after getting results of the Oncotype Dx test, which will be done after surgery if you are HER2- and ER+.
Many more of us avoid chemo since genomic tests like this have personalized care.

Easy to say but find distractions while you wait. And don't be afraid to ask for some temporary Ativan (I did, just 4!).

It's really hard being so young.....breastcancer.org may be helpful for you.
