There was this thread earlier this year, which includes links to posts by two OCFers who have been through this. Note that they have moved on with their lives and no longer post regularly, if at all, but the information may be helpful. And as others here have done, the thread includes recommendations to consult with hospice personnel.

April 2006: Husband dx by dentist with leukoplakia on tongue. Oral surgeon's biopsy 4/28/06: Moderate dysplasia; pathology report warned of possible "skip effect." ENT's excisional biopsy (got it all) 5/31/06: SCC in situ/small bit superficially invasive. Early detection saves lives.
