All of these ideas are great! Here are my thoughts, which intertwine with those already expressed:

AD MESSAGE: (Keep it simple)
_____________________________________________________________
Whether oral cancer is caused by smoking, HPV or factors unknown, the key to successful treatment and long-term survival is EARLY DETECTION.
EARLY DETECTION is achieved through a simple, EASY TEST done by your dentist.
This test may SAVE YOUR LIFE!


SLOGAN SUGGESTIONS: (follow each with,"Ask your dentist!")
_____________________________________________________________
�EASY TEST => EARLY DETECTION => SAVE YOUR LIFE!�

�Stick your tongue out, save your life!�

�Detection can be easy, Treatment is not!�

�Don�t put your money where your mouth is!� (sorry, couldn�t resist ;-})
