Lumpectomy vs mastectomy, immediate vs delayed reconstruction

@samsun welcome to you! 

There are many options, but from what you said you've had a core biopsy? until you have a lumpectomy you unfortunately wont get your definitive pathology of exactly what you have and then what treatment options will be. I know how hard it is, please let us know how you go tomorrow with your Surgeon, as you'll have more of an idea whats next. Hang in there Melinda xo
