Hi Chelee,
Please don't worry! The chemo that you had was recently the subject of a large study that measured the Carbo/Taxol/Herceptin combo against A/C + Taxol & Herceptin. So far, it has been shown to have a very similar efficacy in preventing the distant spread of early stage breast cancer. Even better, it has been shown to have fewer heart side-effects than the A/C + Taxol & Herceptin combo.
Here's a link that may help you...

All the answers are not in, but hopefully this will put some of your fears to rest.
Best,
Jen
