Welcome @"Prime time" it's not an easy place to be...but....coming here will honestly be one of the best things you could have done. There is such an array of experiences and knowledge and the best thing is no judgement. Everyone is very selfless and giving of themselves to help make others path a little easier through knowledge.
So you didn't have a lumpectomy? just biopsy of breast and lymph is that right? so generally the next step from a biopsy is a lumpectomy as the diagnosis comes from that, as it can be different to the biopsy. Its the one way your pathology is definitive. Once that happens you will get your diagnosis, my first in 2011 was DCIS so thats classified as 0 stage, pre cancer. 6 weeks Radiation after lumpectomy and 4 years on Tamoxifen. My 2nd diagnosis in 2015 was 2.5cm tumor ER+ only, Stage 2 Grade 3 and lymph node negative, 6 months chemo and put on Arimidex. 1yr later single mastectomy/diep flap recon. It is an overwhelming time but here are somethings that may be of help.
