Any Mastectomy support groups like Hyster Sisters out there?

I'm a LIW -- surgery date September 22nd -- a very dear friend of mine just found out she has breast cancer, and has elected to have a double mastectomy on July 24th. I told her how wonderful the support group of Hyster Sisters has been, and am wondering if there's a similar group out there for women facing or having gone through mastectomy? I've tried searching but haven't come up with anything? Do any of you Sisters have any ideas where I might be able to find something so that I could share it with her? Thanks so much!

Here's a link to a thread with a question much like yours. There were a few links to Breast Cancer sites posted.
