An update on my husband, Ron, and the mystery mass which showed up on Tuesday's CT scan. Turns out it is a portion of the reconstruction flap they did to "try" to rebuild the floor of his mouth and his tongue. Evidently the portion they put way down into the floor of the mouth has new tissue grown over it. The graft itself appears to the atrophying which they are not concerned about at this point. So the good news is he doesn't appear to have a recurrance! Now I can breathe.
Also, I showed him the info on lymphedema and the massage techniques. Very useful and insightful info from everyone. Thank you so much. Enjoy the day.
