http://oralcancerfoundation.org/facts/stages_cancer.htmStaging also dictates treatments (at least if you want to follow what the big NCI designated institutions are all doing.) There are NCCN treatment guidelines for every stage. And the current standards of care for most, except very early stage OC's, are chemo and rads. You can read the NCCN guidelines for treatment on the main OCF web site.
