Question?? Recurrance of IBC

[to_survivor]

Was wondering if anyone can tell me what the likely hood of IBC coming back after 6 years? Mine was her2 strong and everything else negative.
I did chemo, mastectomy, radiation, and a year of herceptin. They just did a biopsy and I will not know until Wednesday.
I have not had much luck finding the recurrence rate. Any help would be greatly appreciated. Thanks, to_survivor
