@ Mark: I agree with everyone here about the amount of time you should expect to wait before getting biopsy results.

I would like to add that a tonsil biopsy is often a diagnostic tonsillectomy. A primary tumor may be deep within the tonsil and not visible on the surface. Before you undergo that procedure, a scan would be the best first step to locate a primary and any local/regional mets such as nodal involvement or distant metastases...and then, they can go after it surgically.
