I haven't been on this message board in a while but, from the research I've done in the past kidney cancer is uncurable, it can stay dormant or undetected for years but it never really goes away. A second opinion should always be considered and you should look for a GenitoUrinary Oncologist (they're hard to find but it's worth it). My Thomas was dx'd stage4 in Jan 07 and died Nov 07, he had a radical left nephrectomy, he tried Nexavar and Sutent, neither worked I actually think Sutent made him worse. I would suggest that you "keep on" your dad about a 2nd opinion and use
ALL the resources you can get your hands on.
