I am hesitant to respond. But, I will pray for you and your continued health. My father was diagnosed with stage iv Renal Cell Carcinoma on June 27, 2002. He lost his battle on January 15, 2003. They tried interleukin and interferon and the side effects were really bad for him. They had to discontinue treatments after the third treatment. So, if you can tolerate those treatments, it is worth trying. Unfortunately, renal cell carcinoma is hard to fight. One thing is for sure, it is not bigger than God.
God Bless you.
