Hi, my mum was diagnosed with lung cancer and its in her lymph nodes aswell. In March that's all we have been told they said they can't operate because of her age and because she is too fragile. She had a brain scan but they said no cancer there we just swollen lesions that they don't intend to do anything about. They won't even do a biopsy as they say it's unfair to put her through the stress of that...so what I really wanted to know was how long mum might have.Mum doesn't want chemo she said just let it take its course. Other a few things going on with mum especially with her memory I feel like I have been left in limbo because the dr has said he doesn't really need to see her just let her gp do that. I just want to know how quick it may grow.
