When in doubt, go for the second opinion -- at a comprehensive cancer center.

I'd guess that further treatment would depend in part on how invasive the tumor was. In my husband's case, an oral surgeon's initial biopsy of a tiny leukoplakia on his tongue showed moderate dysplasia but warned of a possible "skip effect" and strongly urged further investigation. Since cancer had not yet been diagnosed, he didn't even consider going to a CCC for the excisional biopsy, which got it all and was done by a local ENT.

When that came back with a diagnosis of SCC in situ and a bit superficially invasive (somewhere between stages 0 and 1, we figure), he sent all his records to Johns Hopkins CCC and is now being followed there -- no further treatment recommended at this point.

All the best,
