Survivor since 2010
I also had stage 1 cancer, HER2 positive. I had a lumpectomy, chemo and radiation(in that order). I am not sure if HER2 positive patients always are a candidate for chemo, but your doctor will advise you on the best treatment for your situation. I also was in a medical trial where I did not get herceptin, but was given an oral medicine, lapatnib instead.
