David & Brian, thank you for your comments. I found it strange too that he responded the way he did, Brian you are probably right regarding the negativity part..... I think it was the dentist who did all the extractions she questioned. She has an app. with the chemo oncologist and she may ask him. Today they did the fitting for the mask and as soon as the mouth is healed treatment will begin. It started with a lump on the neck and the surgeon here went in to remove it and sent off the biopsy, after surgery he explained to her husband that he could not get it all because of the carotid artery........ so they decided to get a second opinion at MDA and now she has decided to stay there and let them do the treatment. She is very upbeat and has a very positive attitude so that will help a great deal. Pet scan shows it is confined to the neck. I know from experience she must worry though. All I can do is support her and pray for all who go through the road to recovery, not an easy journey for sure.
