MeierEce, Another test you may end up with is a sonogram-directed needle biopsy. If the small needle biopsy doesn't show conclusive evidence either way, then the sonogram biopsy may be required. I had two small needle biopsies which didn't come back positive, only "suspicious", yet the sonogram-directed biopsy was very conclusive and came back positive for SCC. That after CT/PET/MRI scans that were also "suspicious". Hang in there, don't know whats up until the results are sure.
