Dear Bewildered - I was exactly the same diagnosis!  If there was no lymph node involvement, you really need to get the Oncotype DX test to see if you score high, medium or low for recurrence.  (I was medium low which is classified as a betweener, meaning doctors really don't know how to interpret it).   Also, you can take the Herceptin treatment w/o chemo, (it isn't considered the traditional treatment but you can find doctors who will work with you), and the facts speak for themselves.  Chemo has been around since WWII and the mortality rate for breast cancer has dropped hardly more than 1%, vs. since Herceptin has come on the market, it reduces your risk of recurrence rate by 50%, so if your recurrrence rate is 10%, it reduces it to 5%.  Bottom line - please do your homework and understand what the numbers/statistics are really telling you.   For example, if your recurrence rate risk is only 3%, do you really want to subject your body to chemo understanding all the risks or serious side effects that can occur with it?   The more information you have, the more confident you will feel about your decision.  Personally I'm all about quality vs. quantity....Stay Strong!
