Hi, my nan has just been diagnosed with lung cancer after having a cough for s really long time (first thought to be a smokers cough). I'm not sure what stage she's in, she will be going to the hospital to find out how far it has advanced and they are talking about operating to remove the cancer. My nan has diabetes too. If she has stage 4 cancer (praying to God that she doesn't and that this is just the early stages) what is the likelihood of surviving?
