Well, I felt really bad when I learned I had the brain met, but after talking to the radiation oncs, I feel much better. They told me they would consider doing SRS for up to 5 mets at a time given my age and performance status. They also did not recommend WBR at this time, since I only had the one small one that took quite a while, relatively, to develop. They said, in the event that I do have to have WBR, they would go very slow to try to minimize any cognitive difficulties. The last thing was, that although median survival after brain mets in NSCLC is on the low side, they expected me to do quite a lot better than that because I was an "exceptional" LC patient. They think they can control my brain at this point at least. Oh, they also said SRS was at least comparable to resection, if not better, according to both rad.onc. and neurosurgeon.
Also, if progression is only in brain, your chemo is still working, so that's good news. Hopefully it's just your medicine. When do you get scans?
