I too am Her2+ and worried excessively for months after my diagnosis. I have had 6 out of 18 infusions with Herceptin and have now decided to just stop worrying. I t is very hard to do but my reasoning is that I feel well, apart from lots of Taxotere induced leg pain, and that I am blessed with so many good things in my life that I am determined to enjoy my life "just for today". My oncologist also told me that my chances of recurrence after this phase of my treatment are just the same as if I had not had cancer in the first place (1 in 10). I think I can't do much better than that.
