jc,

You may be right that your brother's hospital sees a lot of oral cancers. My oral surgeon told me he had done his residency in a VA hospital and saw plenty of them while he was there.

However, I'm with those who think you should get a full explanation of the reasons why they want to pull all of your brother's teeth. I had conventional field radiation 17 years ago and have never had a single tooth pulled in my life. (I was 39 when I was diagnosed and am 56 now.) My teeth were in pretty good shape back then and, while I've had to deal with some dry mouth issues, I haven't had to have too much in the way of major dental work in recent years.
