Hey @NewBoobsPLS really sorry that you are here. I have no recommendations for Sydney as I am in Melbourne but just wanted to let you know it sounds like you are grade 3, and fingers crossed not stage 3 pending the results of your lymph nodes. The stage is a scale from 0 - 4 of how advanced the cancer is and the grade is a scale of 1 - 3 of how aggressive the cancer is. If you have a 5mm tumor and no lymph node involvement it should be stage 1. I hope it isn't patronising for me to explain that I just thought in case you are telling family and friends there is a big difference between stage 3 and grade 3.
I have no doubt the other women on here can give you some Sydney-specific advice. Wishing you all the best xx
