Thanks, Sue, for the advice on what to do in case of mouth issues -- dry mouth was also one that I was warned about. I have Biotene on hand and will look into L-Lysine. On Tuesday (1/15) my port will be put in place and then the following day I'll have my first cycle of chemo. Was it ever understood why these problems persisted for you while in rehab?

Interesting point regarding false positives, I wonder if sonograms are better choices.
