Hello I was diagnosed with stage 4 kidney cancer which has metastasised to a vertebrae in my neck. I had the cancerous kidney removed two months ago and had one session of radiotherapy on my neck. There is now no obvious evidence of further cancer at the moment. My oncologist tells me that there will be cancer cells in my blood which are invisible to the naked eye. I have been given the choice of having immunotherapy for the rest of my life or watch and wait and have treatment if and when another cancer materialised. I am in such a dilemma. Has anyone been in this same situation and which road did they go down.
