14 days ago my mum was diagnosed with pneumonia. She ended up back in hospital 10 days later with oxygen sats of less than 50%. They did another xray which led to a ct scan and we were told on the same day that she has lung cancer ( t3 n2 ?0). She has agreed to have a bronsoscopy and a neck aspiration. They did a brain scan but im not sure of the results. I just dont know what to expect. They said its not operable due to the location of the cancer. I just feel so lost .
