Hi Folks,
I live in Scotland ( aged 54yrs) and in Nov 06 was diagnosed with early her2 invasive lobular bc.. I am currently undergoing chemo-on 4th of 8 cycles (having had lumpectomy) but find it hard to get info on her2 prognosis.I will be having radiotherapy and tamoxifen when my chemo ends and then subject to scan having herceptin every 3wks for 1yr.
Can anyone tell me
1 does herceptin delay or stop recurrence?
2 what is best length of time for treatmentwith herceptin to be continued to be most effective?
3 am I right to be very worried about being her2+++ ?
4 what % of people with her2 have disease free survival of 5 or 10 or more years?

I know some of these questions are basic but I feel that you are so much better informed in the US
Thanks Nancy
