Bob,
Thanks for the note and update. The University of Oklahoma is about 100 miles away, and I know couple of people there who could be of help. I had a rather involved tumor removal at age 10 at Mayo, and it has served me well. I'm crowding 76 and still have similar misgivings which I had at age 10. I'm planning to make contact with the necessary players and see what the math problem looks like. Dealing with quarterbacking your own treatment plan, guesstimating the possible cost, etc...I'm going to ask for illumination by their social work committee at both places. They have likely already worked the problem.
Have a nice evening,
Bruce
