I'm not qualified to offer much of an answer to your question, but with respect to staging I suspect you will be catagorized Stage 3 given the lymph node involvement. However, there may be follow-up relative to the nodes to confirm whether there is active infiltration or whether they are simply "lighting up"/reacting to the primary tumor, which was/is the case with me. I suspect you will be going down the same treatment path as me--chemo and/or radiation. The latter has been increasingly debilitating for me--fatigue. Best wishes.
