DX w/brain mets-tumors! Now what?

Had my brain MRI today since I had been dizzy and had an achy head for about a week. I DO have some tumors. I will arrange to have WBR and see what that does. Do I probably get re-scanned after my 10 treatments? What can you all tell me about what to expect? I hope to continue working since I did during all my previous chemo (original) and now (mets to bones and liver). I sincerely hope this works. From what I've read elsewhere, it usually does. Thanx.
