Thank you for your reply and encouragement. I'm not sure about the doctor who is treating my father, his surgery was at a regular surgery center in a small town in central IN (although my father said he is very good and has been treating oral cancer patients for a long time). I've always wondered about the treatment my father-in-law has been recieving (in an even smaller town in central IN), but he doesn't seem interested in seeking second opinions and seems satisfied with the care he is recieving. Maybe if my father can overcome this it will give my father-in-law encouragement in taking a more active role in his own care. Thank you for giving me some ideas for questions to ask and I also wish you the best.
