Yes, I think the waiting was the hardest bit and it is definately better knowing what your dealing with and having a plan. My surgeon didnt talk sentinal or ancillary nodes. He just said he took 18 nodes and cancer cells were found in one of them which is why it was recommended I have chemo. All scans came back clear so there is no sign of it in my bones, organs etc. for which I am thankful. Chemo for me is just a 'preventative' basically. Hugs to you too and keep your eyes on the end of the journey. :)
