Thanks so much for the feedback and comments. We really liked the medical oncologist today and he fully welcomed the idea of a second opinion. We are scheduled for an appointment at the Kirklin Cancer Clinic (UAB) in B'ham, AL on Wednesday. The med. onc. is going to schedule an appt. for a second opinion with an oral surgeon tomorrow. We are still hoping to locate an oral surgeon/dental oncologist who specializes in oral cancer treatment and the exposed mandible.
To answer a few questions ... Mother is in really good health for her age (80 in May) and has a positive attitude. She is quite the fighter! She does have diabetes but controls it with her diet. The most significant problem is her exposed mandible as a result of taking Fosamax in earlier years. She was a snuff dipper up until about 2 years ago.
I feel very fortunate that I have found a support group here. Thank you so much for being willing to share your thoughts.
