As far as I know, Mom's last radiation treatment for this round will be on Wednesday, when we'll hopefully get more news. As of right now, the doctors are still unsure of the originating source, which is important to know for purposes of selecting the appropriate chemo. Uncle Phil mentioned that they may have to do another biopsy, this time of the nodes in Mom's lungs. Lorane and Phil, please feel free to elaborate on this since I really have no idea what I'm talking about (not that that's stopped me in the past).
