Yw, David. Actually, I read something about it from the head and neck cancer Congress meetings held last September in NYC, which Michael Douglas spoke at. It's the first year for this day of observance, and I was only reminded recently from a MSKCC patient booklet I obtained, and the OCF news page. Otherwise, I would have forgotten, and I don't anyone that knows either, but some were glad we have a day, at least to bring attention to this disease. I'm going to a SPOHNC meeting this week, and will mention it there also.
I checked some of the major CCC for any WHNCD events, but couldn find any, at least on this day, and the organization says if not possible, an observance could be made during the same week.
Here is a YouTube video for WHNCD which President Bill Clinton, Dr. Jatin Shah, from MSKCC, Actress Catherine Zeta Jones, and Michael Douglas speak about.
