Wayne --

I do not believe that the sequence is as you describe it, and certainly not all areas identified in a biopsy as dysplasia progress to cancer.

My husband's initial biopsy did show moderate dysplasia, and an fuller excisional biopsy showed carcinoma in situ, with a small bit superficially invasive. But he sees his dentist -- who identified the tiny white patch that was biopsied -- regularly, and she never said anything about hyperplasia, nor did any biopsy report.

All the best,
Leslie
