A member of my family has recently been diagnosed with advanced and aggressive renal cancer that is likely not curable. We have not yet met with an oncologist only a urologist, so we have lots of questions. He is scheduled for a radical nephrectomy but we aren't sure what treatment will be after the surgery. We've been advised that it will likely be immunotherapy but they don't know what type of cancer it is as they are only doing the biopsy once the kidney has been removed. 

Is there a waiting list for immunotherapy patients? Is there a chance he won't qualify for this treatment? How soon after surgery does the therapy begin?

Thanks.
