My diagnosis was a bit different but one lymph had cancer and subsequent axillary dissection revealed no cancer in the lymphs that were taken. Initially the oncologist thought I would need chemo and radiotherapy but I had the prosigna test ($3000. Non rebateable!) the statistics showed that I had an 86% chance of cancer not coming back and 14% of it returning. The onco advised that there would only be a increased benefit of 3% if I had chemo and didn't recommend it . I jumped at the chance of not having chemo and never spent another second thinking about it. I did have radio and that was debilitating enough so I was happy to have one less treatment to my body. My advice is to follow what the medicos advise. Ps despite spending 3k the onco said no guarantee it would not return and I guess that's something we all live with. Lyn
