Thanks for answering. Today's appointments have brought on even more complications to my mom's treatment. The radiologist was planning to begin the treatments next week, but then she visited the dentist who specialized in cancer patients. First, she can't open her mouth wide enough to do the flouride trays that are needed pre-radiation. She also has 4-6 teeth they are talking about extracting and possibly one root canal. All of this will further delay treatment, and she doesn't know how they can do all this dental work if her mouth will not open wide enough for flouride. We're very discouraged today. It seems like just one more blow- and still we can't get started on the treatment that is her only chance of recovery. I'm new to the boards here, but everyone has been so encouraging already. Does anyone have any answers here? Trusting in God, Marie's daughter
