I too have kidney cancer and currently receiving treatment at the xxxx hospital. I don't know you but know that I'm rooting for you. 

You have to will your survival. 

I was diagnosed Friday, I don't know how I should be feeling.  Given a pack to read and just told to wait for the operation appointment to come through.  In the meantime work just keep asking let us know whether we can do anything.  Issue is I don't know day to day how I am  Today I am exhausted, Sunday I managed the gym. I feel a fraud.

I can't put your mind at rest other than to say I know what it's like.
