Help - Advice Needed

[Mandy]

I am desperately seeking info and was hoping you could help me. My best friend who is 56 and was diagnosed with her2 pos bc in late 2002. She went thru chemo but no herceptin. This past Nov she was told its reoccurred in her lungs and bones. She has taken 2 chemo treatments with herceptin. Four days ago she began having difficulty breathing and the onc told her the chemo was not working and further treatments would not help. He told her family to arrange hospice care. Here are my questions:

Should she get a second opinion?
Are there different type of chemo drugs that could be tried?
What is the best drugs to use for someone in her condition.
Should the onc have done a biopsy on the lung tumors and bone to see of they are her2 pos or can he determine this from a serum her2 test?

Thanks for your help!
