Angelrose, I am sorry to hear this, but similar to what minnie56 said, the doctors do not know everything. There are outliers in every disease process - those that beat the disease even though the doctors say it is not possible. A couple of books come to mind: Love, Medicine and Miracles by Bernie Siegel (a physician) and Kitchen Table Wisdom by Rachel Naomi Remen (also a physician). I think you would get a lot out of reading both of them.
Also, if you want to get a second opinion, perhaps going to MD Anderson or Mayo Clinic might be a start.
Sending healing thoughts your way.
