Anytime my mum has to attend the hospital (at least monthly) she won't stay for tests.
Just off the phone with mum who apparently was at the hospital all day after the community nurse sent her there. Found mass? Shadow? on lung in x-ray , needs a CT but... Eh she's not bothered as her breathing is the same (terrible) as usual so she didn't wait because it means an overnight and they will send her an appointment soon.
Sometimes she won't even wait at a&e when referred by GP if it's 2+hours. And to be honest, it's always "fine" in the end up to now.
I suppose we have different views on risk. I find it impossible to deal with her as I know the next 2-3 weeks or however long it takes for the appointment will include her deciding she's dying of cancer , catastrophising etc. She could have just waited and had the test tomorrow
She was diagnosed with pneumonia last week, so maybe just that? But who can tell as NO TEST
