Hi. When is it too late for treatment. My mum has been having scans and tests since February. She has a lung biopsy and now she’s needing a kidney biopsy but we’re still waiting for an appointment. She has now had an appointment come for Thursday to see her urologist?? Do they do biopsies?? Why would the oncologist send her back to the urologist? Would it be because the lung node came back as not a metastatic kidney cancer! I just want her treatment to start so she can begin to feel a bit better. I’m worried the longer this goes on the less they’ll be able to do. They’ve already said it’s not curable but treatable. Any advice would be greatly appreciated x
