So sorry to hear about your brother. Myself, I have a primary brain tumor and was given only months to live - it's been over 2 years!
I have a family friend who was dignosed with brain tumor that had metastisized from her lungs. She is still here over a year later.
Then there's cancer's poster boy Lance Armstrong. His testicular cancer also went to his lungs and brain. And, we all know how well he is doing.
Take care, God Bless,
Pati
