Welcome to the site Steve. Although we hate to have new members it is a great place for people to seek answers and support. There is usually someone here that can answer your questions. And I'm sure someone will that has had a tongue biopsy.
As for the worry, jsut remember as (I believe Mark says) It ain't cancer till the doc says it is... Be sure and explain your worries and stress to your doctor and don't let anyone get away with delaying getting the results to you. With the Holidays next week that might be an issue. Push for answrs. There is no reason for you to go through the holidays with this worry.
Good luck and Take Care,
Dinah
