I was diagnosed with stage 4 renal cancer two years ago, not one symptom except my right knee was hurting and swollen, they found a tumour on my femur, I had a massive leg op and then started on target therapy drug, it shrunk a 9 cm tumour on my kidney to 1 cm in three months, it was tough though, had kidney out October 14, still here walking now without a crutch( in hop spiral 6 months in total) driving and back at work, still on a emotional roller coaster, still on maintence tkn drug, but doing well
