PinkMum,
I am also Her2+ (and I am also ER+, but PR-), my oncologist said that before Herceptin those of us who are Her2+ had poor outcomes, but with Herceptin we have as good, or in fact slightly better outcomes that those who are Her2-, because the Herceptin effectively turns the Her2 gene off.
I KNOW it is scary (I mean - the whole bloody word CANCER is scary and scares the sh1t out of most of the population, with it or without it, and then finding out that you have it is scary, having to have surgery and treatment is scary (we always hear the HORROR stories of treatment - like chemo and radio, never the stories of the people who breeze through it), the side effects they tell us about are scary, this whole bloody journey is scary, but we can and do deal with it and it makes us stronger. i think If I can get through this then I am never goig to be scared by silly things like bumps in the night etc :o)
I KNOW it is hard, but you are not alone, there are many of us here who are HER2+.
You are further along in your treatment that me (I have had 4 of my 6 chemo's, and then have the rest of the Hercepti after that as well as 5 yrs of tamoxifen etc.
