Brian, I don't know why I never discovered it before, but I had never visited the OCF News Section until you mentioned it in your reply above. What a wealth of information! I've been using search engines to find data about the H&N cancer topic, paying for the MOSS report, paying for (a few) full-text studies I was interested in, etc. - and all this time an impressive database on the topic was right in front of my eyes. Thank you for providing such a valuable service. This site is really pretty incredible when one views the breadth and depth of it.
