I just got off the one with the wife of another base of tongue cancer survivor in our village. Her husband is doing great, but his cousin who had the beat the same cancer in 2000 was just diagnosed with early stage kidney cancer. The cousin's doctor in Florida said they are seeing a link between folks who have had oral cancer treatment and kidney cancer. This is the first I've heard or read anything about this...has anyone seen anything proven on this? Brian, particularly interested to hear your thoughts
