Hello - my granddad has been in hospital for constapation - today my mum gets a call say that when they were doing a scan they caught shadowing on the lungs. They informed my mum that my grandad has terminal lung cancer and only a few weeks to live, my mum asks if they had done any biopsy or bloodwork and was informed that she was a specialist and didn't need to... a hour later Mum gets a call back to say another specialist has seen the scan and actually my grandad is completely fine - no cancer - just needs to come back in 8 weeks for another x ray. We now don't trust anything we are being told and feel something is not right? Does anyone have any advice?
