Good they are pushing those tests through before the surgery. It's called 'staging' and once they have the full pathology report back after the surgery they will all get their heads together and plan a treatment and time line thereafter. Make sure you ask for pain meds (proper ones, not just Panadol) before you go home from hospital. I had just Panadol after my first op, mastectomy and one node removed and it was flipping painful once I got home and the hospital meds wore off. My sis in law once said of the hospital system if you don't ask you won't get so after my second op, to remove all the rest of the lymph nodes since the first nodes pathology was positive I made sure I asked for pain meds to take home. Sooooo much easier. <3
