Help, Herceptin weekly?

[Snufi]

Hi to all, Had an appointment with the nurse today to go over chemo treatment scheduled for Wednesday. She tells me Dr. wants to give me TCH every 3 weeks but also herceptin every week for the next 18 weeks and then to complete a year. This is the first I eard of this. My dr. told me last week herceptin given every 3 weeks with chemo. The other 2 drs consultes with told me the same. Has any of you heard of Herceptin every week like this for Stage 2A. I told the nurse I wanted to stick with the every 3 weeks treatment and she said okay. why did she even bring up the herceptin weekly for the next 18 weeks? Am very confused.
