Hi GinGin,
Well welcome to the community, one you'd rather not be part of but is such a great source of encouragement.
I was 4 weeks between diagnosis and surgery, I had more biopsies MRIs and mammos in this time. As part of the biopsy they should have done immunochemistry markets which tell you hiw fast it grows (K 67 marker) and if hormone receptive ( estrogen, progesterone or hetceptin). The big picture dictates planning and any presurgery treatment. I didn't need cgemo before or after, but am about to finish radiation, then ho on hormone blocking therapy for 5 to 10 years.
BC is very heterogeneous, so it's hard to compare each other's treatment etc
Good luck with it all and my best advice is to ask all of the questions that pop into your very busy mind. I take a book to write questions and answers in.
Take care x
