Here's another list of CCC's (Nat'l Cancer Institute designated) from this forum:

The CCC's have to earn and keep up that designation, it's more than just putting more than one discipline under one roof, things like establishing a tumor board and having it meet at least once a week to discuss individual cases and make recommendations.

What is "skip effect"?

I had numerous biopsies showing leukoplakia and dysplasia across 15 years before a tumor actually started growing at that site on my tongue, so it can be a long process. None of the ENTs or oral surgeons would say that cancer would occur, just that I had to be watchful for any changes in that site.
