My Dad was diagnosed with extensive stage small cell lung cancer 12 months ago, it was later found to have metastasized to his brain. He's had chemo, and radiation to brain and chest. On reading his most recent brain scan the doctor told my parents all they could see was scar tissue from the radiation so does this mean the radiation has worked on the brain mets? His most recent chest and abdomen scan has been described as stable but what this meant wasn't explained to my parents. My Dad has previously been told by his doctor that it's just about how much time they can get for him now and he won't be able to be cured. My parents live in Ireland so I'm not able to be there for all his appointments to ask questions and they don't ask them when they are there so I'm just really confused about where he is up to now.
