I agree with you completely. When I started this website, I discovered that while there were several information leaflets on mouth cancer prevention and detection, only limited print runs (limited by sponsor's funds) had been done to promote Mouth Cancer Awareness Week. And a new leaflet was designed each time to carry the new sponsor's advert. They were not easily available and dentists weren't as aware as now.
So I tried to compensate for that by making material available through the website. I have made the World Cancer Research Fund's "Mouth & Throat Cancers" leaflet (PDF format), available on the RDOC website's homepage. It was given out to dentists at the British Dental Trade Exhibition during the launch of the MCF. Most UK dentists have a poster and some information I would think. It is getting better. The WCRF leaflet is also sent out by them to GPs. But I have not seen anything on mouth cancer in my GPs surgery yet .
In the past, there were no organisations soley focussed on Mouth Cancers in the past. The Oral Cancer Foundation (USA) and the Mouth Cancer Foundation (UK) are making a start. We will get there.
