My grandfather is 82 and has been diagnosed with lung cancer , at the beginning we were told he would need radiotherapy as surgery was not a option for him (he also has COPD among other things ) so he has the treatment done, and managed extremely well with this ! All was looking well , but I was shocked when he went back for his review and was told he wouldn't need to be seen for 3 months and they didn't ask for a chest X-ray or anything , so I'm just curious as to how they would know it was all ok , without doing this ? I have also noticed a massive change in his behaviour since the diagnosis , he seems to be more impatient and angrier than normal ? Is this to be expected to? He lives with us permanently so I could care for him , but I am finding our relationship strained due to his change in behaviour .. can anyone be of help or any advice ? :)
