I have a recent diagnosis of 10cms kidney tumour which has grown into the vena cava vein. No metastasis. I have been advised that I can have immunotherapy to try and shrink the tumour which would then make the operation easier and safer. However if the immunotherapy doesn't work I cannot then go on and have the op. The 2nd option is to take away my kidney with a vascular team to remove the growth in the vein. Followed up with immunotherapy. My other kidney is not working well so I would have to have dialysis afterwards too. My consultant has warned I may nor make it through the op lots of complications stroke, pneumonia etc etc I am 74. I immediately opted for the op to hopefully get rid of the cancer now I'm having doubts. Has anyone else had this op that can comment and tell me their outcome thanks.
