Hi Chrisann:
I also experienced this with my husband. Did you speak with the drs. and what are they saying? Renal Cell Cancer is a sneaky cancer. Can they try another drug other than the Sutant. I would ask them if they can use the Torisel. Maybe that would be better for your dad. I think they give it IV and some people say the side effects are not as bad as the Sutant. If you want anymore info please let me know.
Can they do radiation?
Best regards
Bernadette
