Herceptin questions

[KCC]

Hi-I am new to this board--I was wondering if some of you would answer the following questions for me as I start Herceptin tomorrow---

1)I will have my last chemo (Taxol) tomorrow, my onc wants to start me on Herceptin tomorrow---is it okay to get Herceptin and Taxol in the same day?

2)What are some side effects that I will experience on Herceptin?

3)I will have a mastectomy (possibly bilateral) and recon in November---Is it "heart" safe to be on Herceptin and endure such a surgery? (I plan on using my own tissue in recon)

thanks so much.
