Hi @ishaz, there is lots of great advice on here about treatment, look in the tests and treatment board specifically.
@kezmusc is right, there are lots of different types of Breast Cancer (who knew!?) and you will come to find what yours is, and what the treatment program is going to be.
Be informed is my advice, ask lots of questions and keep up the exercise so you are fit and healthy for surgery and treatment.
Oh and I just thought of something someone told us, we recorded my first appt with the oncologist and it was so good to be able to listen back to it without the stress of the day. Most doctors seem fine about this.
Take someone with you too so they can remember bits you don't.
Good luck with it all.
