Hi, @nab – since you were talking about stereotactic radiosurgery (SRS), I moved your post here where others have been talking about the same subject. Hoping @janoh and @mrser52 will join this discussion and offer some pros and cons for doing SRS. @merpreb@dreamintwilight and @IndianaScott also may have some thoughts for you.
Did your doctor offer you reasons for recommending the whole brain radiotherapy? If so, what did he or she say?
