Herceptin without Chemo???

[Mariam]

Hello,
I feel that I'm losing my mind. There have been differing opinions regarding my treatment with Herceptin. I wondered if anyone has experience or thoughts to help.

I'm 44, at 32 I had breast cancer (infiltrating ductal carcinoma)one lymph node positive- lumpectomy, chemo, and radiation. ER positive negated 5 years of Tamoxifen, 5 years Lupron/Zoladez injections with Arimidex pills.

Recurrence seen by mammogram this August. I had a masectomy. The tumor size is small .6mm but now HER 2 positive. Two cancers now infiltrating and insitu ductal carcinoma (They did not have HER2 testing previously) Oncologist wants to treat with hormone and Herceptin without chemo. HAS ANYONE had Herceptin treatment without chemo? Another oncologist indicated that it wasn't as effective. PLEASE HELP.
