Lung mets suspected. I need info and support

[Linda]

Hi friends.
I don't post often -- actually I've sat back and read a lot, but now I'm really in need of info and support. I was dx her pos, hormone neg, stage 3a a year a half ago -- did A/C. taxatere, radiation and finished my year of herceptin in August. I'm 53 with a great husband, job and 2 kids.
I knew I was high risk (I had neo chemo, but was left was one pos node and a large amount in the breast -- and my path is all super high) thought all was NED, but just had a scan that showed a 9mm cavitary lung lesion (on the bc side.) It's not the usual way for a met to look, but considering my history...a Pet will soon follow and a lung biopsy.
What meds have any of you used in this situation? Has anyone had an open lung biopsy (I'm hoping for a needle biopsy, but don't know.) and how hard is it? Has anyone had a lung met AFTER a year of herceptin, and if so, how are you doing?
I know many of you know how I feel right now. Anything you can tell me would be appreciated.
Love
Linda
