Hi Shazza,
I am 39 have 3 children (11, 13 and 19) and have the same tumor as you.
Mine was 30mm ER/PR/HER2 pos. my sentinel node was clear yay! So I am having 4 AC (have had 3 already) and 12 Taxol/Herceptin then 7 weeks of Radiotherapy and continue the Herceptin for 12 months and some kind of hormone blockade. My doc hasn't decided yet.
I had a port put in just before Cycle 1.
The "fabulous" thing about all of this is that I am a cancer nurse so I know everything that is going on, am being treated by friends and ex colleagues and could probably give my own chemo.
In the beginning I thought knowledge is a curse but I now see it as a blessing.
Hope you get through it all ok
