Hi JuneXie,
I was diagnosed Hormone + in 2018 and had chemo first, then SMX with nodes removed (1 showed positive) and then rads.
My SMX showed the breast tissue had responded to the chemo. I'm not sure why it is done in that order though. All subsequent US and mammograms show no sign of anything now which is great.
I found chemo to be a pretty good experience with minimal discomfort (except for the hair loss bit). I was able to walk a lot and had only a couple of days of really bad fatigue.
Write down all of your questions for the Dr and BC nurses they are really helpful! And that way you have a record of their answers.
Wishing you all the best.
