Here is a wire service report about another "spit test" developed by researchers at UCLA (Brian, is the the same one you referred to earlier in this thread?). I am sure the journal article referred to will show up in the OC in the News feed (as will this Reuters article) but I haven't seen either one yet -- hence this post.

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.
