So my dad had lung cancer last year stage 2. He had half his lung removed then radiotherapy. We’ve just been told it has came back and is in both lungs. We’re waiting on further scans as they want to check his brain. They said the tumour in his right lung is 1.8cm and one in left lung is less than a cm. What is the likelihood for treatment following this? And is it something I just need to prepare myself for that they can’t help him? I feel like I need information on staging and prognosis to be able to deal with this to help him. Any information would be really appreciated.
