Hi everyone. I'm new to this. I really need help with my diagnosis that my cancer spread after 10yr. Went for my 10yr ct scan and found a small tumour in my remaining kidney. I'd had a partial nephrectomy 10yr ago. And a tumour in the lung . All the they said about size of the tumour in lung was 'larger. 10yr ago it was 3mm so they left it and it's never grown. What im asking is that the doctors last week said they start me on tablets to shrink the tumour but now they've change the mind. Yes it is small the kidney tumour 1.5inch but I only have 2.5 left. I can't have chemo or radiotherapy due to being in renal failure and removal will put me straight on to dialysis. Can anyone explain why the doc said they monitor it rather than treat it.
