It was odd, whenever Mom had symptoms that appeared to point to brain mets, her scans came back clear. When she had her first mets, (discovered when she was symptom-free) they were easily dealt with through Gamma. After her last ones were discovered, she was just too tired of the process to keep going, though her radiation onc. said it could have a favorable outcome.
I have a friend whose husband has survived 8 years after a nasty brain met. There are amazing strides in tx.
Hope everything turns out to be hunky-dorey.
