I agree, Go see Dr. Tannir. I promise it is worth the trip. My husband was originally diagnosed with Renal Medullary Carcinoma and Dr. Tannir really broke it down to look at my husband as an individual and looked to find a treatment that is best for him and reassured us that we were not at a brick wall where there were no more options. This is where we were getting at home being that he has been getting treatment since April 2011. It is an amazing facility as well!
Good luck! Prayer is also great medicine. I recommend setting up a caringbridge site for family and friends. It helps to get positive messages from them and then you only have to relay things once. My mom keeps up my husband's site for us.
We will be praying for your family.
