I finally heard from the doctor this morning. There was a glitch in the computer system which held up the results being posted which is why it took 8 days. The results are negative which means there is no cancer in the lymph node. (Yay!!!). This means that during surgery they will most likely remove fewer lymph nodes, as the plan is to do a sentinel node dissection.
Thanks to everyone who has been checking in on me and the biopsy results!
