To treat or not to treat VERY early stage HER2 IDC

[weety]

I believe that when I was diagnosed with a 7mm tumor in 2009, I was told that ASCO's guidelines for that size was to "consider" chemo/herceptin. The under 5mm's recommendation was NO chemo or herceptin. I think since then, though, they have found that even small HER2+ T1a and T1b tumors (1mm-9mm) recur at quite alarming rates, even when nodes are negative--I think I read that 23% had recurrences! So, I think the new guidelines, based on this info, is that the "consideration" chemo has shifted downward--Now anything over 5mm is a definite recommendation for chemo, and the under 5mm group is the "consideration" group. I'm not sure what I personally would do with yours (2mm) but I do think you fall into that consideration group--I would not automatically accept that you don't need any more treatment. Get some expert opinions before you make a decision. You are right, this is your life you are talking about!
