Jennifer, it sounds like an insurance issue to me. Herceptin is very expensive, and although many oncologists are now giving it to their Stage III patients in hopes of staving off a recurrence, it's isn't actually FDA approved for earlier stage cancer; SO, if you have insurance, you would have to make a case for pre-authorization, hopefully with your onc's help. Then the hospital will be assured that insurance will cover the cost of the drug. If you don't have insurance, contact Genentech, the makers of Herceptin, and ask about their patient assistance program.
Here are some links to info that may help:
