Letrozole treatment for Secondary BC in lungs

My Mum was diagnosed in Nov 2010 with secondaries in her lungs and the onc now suspects that the lumps on her temple are more mets on the skin. Early stages at the moment; she has been on Letrozole for 3 months and we are waiting to see if this is working to stop all the mets from progressing any further. Mum has been through a lot of down points since this diagnosis but has scheduled some counseling and might look at some massage to try and help her cope. Anyone have any similar experiences or advice that I can pass onto her? She is thankfully not symptomatic at the moment but we are not sure how long this will last.

I have to say that having read a lot of the posts, this community has given me such hope for my Mum. There is so much strength out there.
